LHCb

Things we want to do

Ideas for the exhibitions

- simple hands-on experiments

- maybe experiments for classes in the teachers lab

Teaching outline- pre, during and post visits

AD (Antimatter Factory)

Things we want to do

Teaching outline- pre, during and post visits

Ideas for the guided tour

- simple hands-on experiments and demos

- ideas of what to show (and what not to)

- new posters

Quadrupole

Pre-visit (ideas) – LHCb and AD

Text for the teacher- a not too complicated text for the

teacher to get some background info (not too simple either)

A ppt-’suggestion’- a pre-prepared ppt in a editable

format so the teacher easily can add and subtract pictures, text etc. to make the presentation suited for the specific class

A web based resource place

- with the best pictures, animations and links

Pre-visit (ideas) – LHCb and AD

- questions and problems - hand outs to the students

(conceptual and problem solving) – editible format

Neutralino

LHCb - outline

Before visit- articles only for

the teacher

- introduction to

the standard model and the LHC (ppt, animations and games)

- Antimatter and the role of the LHCb (text and videos)

- Introduction to the LHCb (text, virtual tour)

- Studying the sub-

detectors

LHCb - outline

The Velo:Calculating the time of flight for the b-quark knowing its lifetime.Reconstruct paths of secondary particles to find a common production point.

The Rich:Calculating the velocity using simple trigonometry.Find circles that fits the measurements and then find the diameter of circles to get the velocity.

LHCb - outline

The magnets: The force on a charged particle in a magnetic field.Drawing the curved trajectory from the straight line trajectory before and after the magnet to find the radius of the trajectory in the magnetic field.This can be used to find the numeric value of the particles momentum.

That’s a great idea! Cheers

mate!

LHCb - outline

The calorimeters:Learning the principle and maybe calculate things related to bremstrahlung and also to the collection of the photons by the optical fibers (e.g. internal reflection). The muon system:Learning the principles about gas filled chambers by comparing it to the GM-counter and maybe calculating the position from the drift velocity and the time. Several simple calculation can give the trajectory.

The exhibition (ideas) – LHCb

What is the story- What are you doing- Why are you doing it

Symmetry in physics- Energy and symmetry, example: two billard balls central collision- Momentum and symmetry, example: two billard balls off axis collision- Angular momentum, example: the balarina


Symmetry violation- Missing energy in beta-decay =>Discovery of the neutrinoDiscoveries in the early days – cosmic raysDiscoveries in detectors

Why LHCb?- Investigate the symmetry violation of the beauty quark- Which decays are we looking for?What are we expecting to find?


The large detector model- Connect each part (velo,…) with a red wireto a short explanation on the inside of thewindow to the box, or to a button that controla touch sensitive presentation screen, where a web could costomize the explanationdepending on the needed level of detail.- Use a picture of the model as frame of reference in the following detailed description of the detector


The ’real life’ detector elements- Nice that you can se what the elements look like scale 1:1- Place a little picture of the model highlighting

where the element (velo,…) is located- Give a short explanation of how it works, use

everyday examples like, the velo works like a ccd camera (little drawing of each), the calorimeter thermal solar panel

The measurement data - What are physisists doing, the

dataprocessing, an example where you can see the tracks, steel from Atlas

Z-boson

Filters

Slit

Diffraction Grating

Lamp

Students use grating to separate frequencies of light. Filters are used to discriminate relative energies by eye or light meter.

Calorimeter analog

The exhibition (demo-ideas) – LHCb


Prism-dispersion-analogy- same principle as the bending of the

beam by the magnets

Bending e-beam with magnet

- maybe using an old monitor that loops a film showing a dot in the middle of the screen (you can put a coord. system on the screen and take measurements)

Light-guiding with mirrors - to catch circular pattern from the CR

Tracker analog

Ramp

Magnets

Marble

Students can compare path of marbles with different masses and or starting heights.



‘The LHCb-collaboration’

- a class gets divided into groups. As a whole the class is studying a collision-event in ths LHCb, but each group studies only what happens in a seperate part (layer) of the detector. Ind the end they piece together what happened form the moment of collision untill the end of the detector

…this can probably also be done before or after a visit to the LHCb…

CP-violation

• Good content for general public• Nice layout• Good videos

• More detail, higher level• Information on the experiments• Pictures, diagrams etc. • Not updated

• Great stuff on traps, detectors etc.• Pictures diagrams etc.• Not updated

Examples

AD - outline

Suggestions- Add a section ”For teachers”

- More technical details

- Powerpoint to be used in class

- Prepared (short) exercises and where they fit in the physics that are being taught

AD - outline

Before visit- General antimatter (pair-production, anihilation)

- Special relativity (energy needed to create antiproton, speed of particle)

- Electromagnetic fields (acceleration, right hand rule)

- Thermal motion of particles (temperature, velocity, energy)

- Preparing questions for researchers

AD - outline

After visit- Projects. For example:

Historical perspective

Misconceptions / myths in media

Antimatter regions in the Universe

Other antimatter facilities?

Bubble chamber

Before visit - Theory:

Gamma rays, Interaction with matter, the exponential decrease of energy for gamma, ParticlesThe body is close to empty:Particle – particle interactionLinear Energy Transfer defined by dE/dx. Stopping power and rangeUnderstand why particles are better than x-ray in killing tumors and limiting damage to sensitive organs and tissueHistorical development, from tubes to Co-60 hospital equipment, Issues solved.

AD – medical aspect - outline

Exercises: simple calculation of dosecalculation of dose delivered to tumor and

to critical organ from x-ray pictures, depth/energy/dose- graphs,

Planning a treatment, simple example showing key principles

Experiment: Gamma through water


During Theory:

What are the problems and questions that CERN-ACE tries to solveOH-presentation (’15 h)Discussion and exercise:Find critical points in the experimental set upsimple calculationsVisit to Bern, practical particle therapy - optional

Experiments: How is the experiment set-up – (poster and handout (A3 folded to 4*A4))What are the findings until now – (poster and handout)Unanswered questions Plan going foreward


After Broaden the scope to include the plans for

development of particle therapyWhat is the status of cancer treatment in my country.What are the plans for development of the therapy possibilities.What is the attitude among patients, doctors, decision makers and organisations.

The guided tour (ideas) - AD

Monitors from the control room

- in the control room there is monitor showing the protons hitting the copper target every 2. minute…this should be displayed for visitors

- model or screen showing the process (production of the anti-p -> slow down in the ring -> entering the various experimental sites)

- map of the facility

The hands-on activities an demos

- marble-potential, polystyrene ball trap (demo)

- real equipment (quadropoles, RF-cavities,…)

The answer…

…to the question:“Should we [Mick Storr] keep sending people

[visitors] to Point 8 [LHCb]?”

And the answer is:Yes, if you can make room at point 8 for the demos (a least twice the size it is now)

No, if you can find room at CERN for the LHCb exhibition + the demos

Wino

AD - outline

Before visit If you want to prepare a visit with a class to AD the teacher wants to knowWhat are they looking for?How does the machine work?Where can you use AD as an example in high school physics?

Theory What topics is it useful to cover before coming to AD?

How do you use AD as an example when teaching those topics?

Note: These are topics that are generally taught in high school physics. The idea is to use AD as an example

while covering this in class.

AD - outline

General antimatter Being familiar with what antimatter is. Antiproton, positron, pair-production, annihilation, etc.

Special relativity- Being able to use E = mc2 to calculate energy required to produce antiproton.- Calculate the speed of a particle with certain energy (relativistic).

Electromagnetic fields- Doing basic calculation of acceleration and deceleration of charged particles in electric and magnetic fields- Right hand rule

AD - outline

Thermal motion of particles- Doing basic calculation of the thermal velocities of particles of a given temperature- Understanding the relation between temperature, kinetic energy, velocity

Vacuum pumps ExercisesI have only made on example of an exercise. The idea is to show where the level should be. It is also likely that not a lot of time can be spent in class going into detail. Therefore the exercises should be fairly short. It would be nice if the details (energies, field strengths etc.) could be somewhat accurate.

Preparing questions for guide/researchers. For example:- What is the latest findings?

During TheoryThe pupils could be given the task of finding the answers to a few questions about the ADFor example:- In what ways are they trying to compare hydrogen to antihydrogen?- What are the problems with storing antihydrogen?- Simple calculations as the one given above. Experiments- Finding answers to unanswered questions

AD - outline

After There could be projects for groups of pupils where they could dig a little deeper into antimatter research. For example:- Historical perspective.- Other places that are doing antimatter research.- Could there be regions of antimatter in the universe? How do we look for it?Alpha Magnetic Spectrometer- Misconceptions about antimatter. Can it be used as energy source / bombs / interstellar travel?- CP-violation
