1 A short introduction to the Summer Student Hardware Labs Olav Ullaland, EP CERN

2 The Summer Student Hardware Labs (even in software) With the size of the experimental tools in high energy physics getting larger and more complicated, it is very hard in some short summer months to get a feeling of the different aspects of an experiment.

3 We would therefore like to invite you into some of our labs and try to show you in a few hours what we are doing there and why we are doing it. http://www.geocities.com/dlazechk/indexa.html Andre Augustinus Tito Bellunato Andre Braem Carmelo D’Ambrosio Lau Gatignon Christian Joram Beat Jost Niko Neufeld Emile Schyns Who are "we" :

4 West Area Test Beam facilities Organisers : SL/EA group Contact person : Lau GATIGNON Optimisation of a beam line by using collimators, bending magnets and targets. Particle identification with Cherenkov counters and absorbers.

5 Slow controls - Real time Programming Teacher: Andre Augustinus Requirements: The workshop is aimed at students with no experience in controls Time : one afternoon, 14:00 – 18:00 Dates : 6, 7, 8 and 9 August Place: to be announced The workshop is intended to show a case of real time programming and controls, using as example gas pressure and/or temperature stabilisation. It will include the use of control software packages as well as handling of hardware like flow meters, valves, pressure and temperature probes. Encyclopædia Britannica

6 Production and Characterisation of Evaporated Thin Films Teachers: Andre Braem and Christian Joram Requirements: none Time : one afternoon, 14:30 – 18:00 Dates : 15, 17 and 19 July Place: 3/R-020 Generation of high vacuum; evaporation of thin films; optical transmission and electrical resistivity of thin films; quantum efficiency measurement of photocathodes. http://www.levity.com/alchemy/images_s.html

7 Mirrors and Light Teacher: Tito Bellunato Requirements: none Time : one afternoon, 14:00 – 18:00 Dates : 4 groups first two weeks of August Place: 17-1-007 Perform measurements of the radius of curvature of a spherical mirror and its average geometrical deviation from the ideal spherical shape. Such mirrors are used in Rich Imaging Cherenkov (RICH) detectors at CERN. Composite, Beryllium and glass substrate mirrors will be used. Encyclopædia Britannica COMPASS

8 X- and Gamma- rays detection with a Hybrid PhotoMultiplier Tube Teacher: Carmelo D’Ambrosio Requirements: none Time : one afternoon, 14:00 – 18:00 Dates : 4 groups first half of August Place: Meeting place will be given by e-mail Please note that gamma sources and high voltages are present on the set-up. New Scintillating Crystals are being developed for bio-medical applications, which were first developed for high energy physics or material science. With a new generation of photodetectors being made available for the same applications (HPMTs, APDs, SDCs, etc.), these gamma detectors (crystal + photodetector) represent an important contribution in the evolution of instrumentation for physics and non-physics applications. Encyclopædia Britannica

9 Quantum Efficiency of CsI Thin Films in the UV-Region Teacher: Emile Schyns Requirements: none Time : one afternoon, 14:00 – 18:00 Dates : 3 groups last two weeks of August Place: Meeting place 1/R-031 A 300 nm thin CsI-film has been deposited onto a gold-plated pcb- substrate. In vacuum a VUV-source and simple optics illuminate the sample with a well defined UV-light spot. The measured photo-currents from the CsI-photo-cathode are in the pico Amperes range. To obtain the Quantum Efficiency of the CsI photo- cathode, the total photo-current is measured by replacing the sample by a photo-multiplier with a well know Quantum Efficiency. http://www.levity.com/alchemy/cab_min1.html The stone of the wise

10 Data Acquisition (and fun with bits lost and found). Teachers: Beat Jost and Niko Neufeld Requirements: Some basic programming experiences would be good - but that should not deter anyone. Time : one afternoon, 14:00 – 18:00 Dates : 4 groups 26 - 29 August Place: Meeting place 2/R-019 DAQ systems at LHC will have to move huge amounts of data (several GB/sec) operating on links which run at 1 GHz. Students will have an opportunity to see a prototype system for the LHCb data acquisition. You will be able to operate and modify high speed network switching code. The software can be experienced on real hardware as well as closely monitored in graphical simulation programs.
