WHAT IS CERN@SCHOOL?A brief introduction to the project

CERN@school: an introduction
• Brings CERN technology into the classroom:– To aid the teaching of particle physics;– To allow students and teachers to do research;– To inspire the next generation of scientists/engineers.
• Different ways to get involved:– In-school detectors – through SEPnet and IoP;– LUCID: 5 Timepix detectors on TechDemoSat-1;– Data shared by students and teachers.
• Currently supported by an STFC Large Award.

CERN@school: who’s involved
• Project Leader: Dr Becky Parker• STFC Research in Residence: TW• GridPP support: Chris Walker, Steve Lloyd– Queen Mary PPRC computing - huge thanks!
• The students:– Mainly A level, some GCSE;– Technical ability varies – but research work
Colour corresponds to the “Time-over-Threshold”, which corresponds to the energy deposited in the pixel

The data

The data
• 256 x 256 frame of pixels:– Output in ASCII or binary, matrix or [X,Y,C];– Meaning of pixel value depends on mode:• Time-over-Threshold – time spent over preset
threshold value (corresponds to energy).
• Associated meta-data:– Detector settings, location, time, etc.
• Various formats exist: Pixelman, NASA’s ROOT-based format, .LSC (based on FITS).

GridPP activities
• The CERN@school VO: cernatschool.org• Running CERN@school jobs:– “Hello World!” (obviously);– Custom software via InputSandbox:• CERNatschool-frame-reader (on github);• Sample frame data on figshare - http://dx.doi.org
/10.6084/m9.figshare.644460
– All documented on the GridPP wiki.• Huge thanks to the QMUL GridPP team!
• Data storage and retrieval:– Timepix data collected by schools uploaded via an
online portal, LUCID data from SSTL managed and uploaded by CERN@school team;
– Data processed (cluster analysis etc.) on GridPP;– Results available via same online portal.
• Storage/processing needs mat by DAQMAP:– Not (yet) enough demand to justify x certificates.

The revised plan
• Simulations with GEANT4:– Timepix detector and (shielded) sources;– LUCID in the space radiation environment.
• Example use case:– End user (student) requests events for given source
type, energy range, flux, etc.;– GEANT4 run on GridPP, managed by CERN@school;– Simulated data retrieved for analysis.
• Compare with National Schools Observatory.#GridPP30, Uni. of Glasgow 27th March 2013

HOW BEST TO USE GRIDPP?Thoughts on data analysis/simulation for student-driven research.

Lessons from CERN@school
• Choosing appropriate research tasks:– Where can GCSE/A level students contribute?– Task complexity and “gateway activities”;– Chris Lintott (Oxford, Zooniverse) – blog post:• “transformational nature of [doing] something real”.
• Getting students to code:– Scientific research provides huge motivation;– Challenge - school IT infrastructures vary…
• What else could we use GridPP for?– With the right research task, plenty of Impact-
worthy and scientifically useful projects out there.• What could we use the Cloud for?– Our experience: give the students the tools and
they will do amazing things.• Can we integrate impact from the outset?– #OpenAccess, #OpenData - reproducability?

CERN@school and GridPP
• Bringing technology from CERN into the classroom – and doing the same for GridPP;
• Much progress made over the last 6 months:– Plenty still to do – your input very welcome!
• Huge opportunities for research + impact:– Much learned so far – please ask us!
