Using Digital Pens for Physics
Francois Grey, CERN IT Department
mini-workshop on augmented paperOxford 27 September 2006
The LHC
27km circumference accelerator …
… maintained at -270C.
ATLAS
150 million sensors …
… read 40 million times per second.
LHC data
LHC data correspond to about 20 million CDs each year
Concorde(15 Km)
Balloon(30 Km)
CD stack with1 year LHC data!(~ 20 Km)
Mt. Blanc(4.8 Km)
Where will the experiments store all of
these data?
LHC processing
LHC data analysis requires a computing power equivalent to ~ 100,000 of today's fastest PC processors
Where will the experiments find such a computing power?
Computing for LHC
• Problem: even with Computer Centre upgrade, CERN can provide only a fraction of the necessary resources
• Solution: Computing centers, which were isolated in the past, will be connected, uniting the computing resources of particle physicists worldwide

Overview
• OpenLogbook: a new approach to recording and reviewing experiments
• Do particle physicists need digital pens? (Short answer: yes!)
• combining OpenLogbook and digital pens: results and prospects
openlogbook is an application for reviewing multi-dimensional data from different kinds of experiments.
Basic Philosophy: Store everything (on the Grid)review synchronised data, annotate online or offline with “hotspots”
Alpha-testers include:Fundamental science (ATHENA, CERN)Applied technology (MIC Cleanroom, Copenhagen)Social science (Imagination Lab, Lausanne)
What is OpenLogbook?
2001: OpenLogbook conception at Imagination Lab
2002: OpenLogbook V1.0 by student team at CERN, first test
2003: OpenLogbook V2.0 by student team in FinlandTested by nanotech lab, social scientist, ATHENA experimentATHENA requests integration of paper logbook into OpenLogbook
2004: Develop web-based sharing of HP digital pen data for ATHENASuccessful test of digital pen solution by ATHENA Develop digital paper guestbooks for CERN 50th anniversaryStudent team sponsored by HP
2005: Integrate HP digital paper solution with OpenLogbook V2.1
2006: Develop web-based sharing of IO2 digital pen dataDigital pen survey requested ATLAS experiment (>20 persons)Integrate IO2 solution with OpenLogbook V2.2

Deployment at ATLAS
…word of mouth leads to >15 more test users!
Three types of user:
Taking notes (managers) Covered by commercial notebook solutions
Data logging (technical staff) Covered by commercial forms solutions
Extension of e-log for sketching etc. (scientists) Potential for logbook (&OpenLogbook) solution
Results of Survey
Strengths
1) Sharing paper on web2) Portability of paper3) Recording of sketches
Weaknesses
1) No cut and paste solution2) Not available on MAC/Linux3) No annotation solution
– Use stroke time-stamping to integrate paper logbook completely
• Decode string in XML?
– Develop simple way of integrating pasted items • Print bar code?• Print on digital paper?• Use OpenLogbook for plots?
