Belgian Groups in the Project

February 5, 2010 RPC Upscope Meeting

In the upscope plan put forward in 2008, the Belgian contribution to the chamber assembly/testing would be

distributed over 3 sites :o VUB : Walter Van Doninck et al.

Installation & commissioning of RPC endcap system, mechanical design of upscope chambers

o UCL : Eduardo Cortina et al. RPC detector R&D

o UGent : Michael Tytgat et al.Commissioning of RPC endcap system, simulation studies for RPC upscope, RPC

detector R&D

Belgium would assemble/test enough chambers to instrument 1 new endcap station 2 (low η part) : 72 chambers + spares in

total, RE2 or new RE2bis “double” chambers, 36 RE2/3 in Gent, 18 RE2/2 in Brussels, 18 RE2/2 in Louvain-La-Neuve

Similar assembly procedures and detector tests foreseen as in the ISR, before detectors would be shipped to CERN

Central coordination of the Belgian contribution by Gent

Status of RPC Labs : VUB

RPC lab under construction : o assembly/test room availableo gas mixing unit ready, gas bottles to be orderedo CAEN HV/LV units readyo infrastructure ready (tables, electronics racks …)o setup for gas gap pressure and HV tests readyo no cosmic test bench

Lab could be operational on short time scale

Status of RPC Labs : UGent

February 5, 2010 RPC Upscope Meeting 5

Large RPC lab under construction : o ~ 70m2 area for assembly/testing allocated in old accelerator

hall of the institute; additional space for storage of chambers and material available

o additional new detector R&D room (45m2) being set up o air conditioned hut (19m2) ordered for chamber testing in a

controlled environmento gas mixing unit (built by CERN gas group) delivered; to be

installedo CAEN HV/LV units readyo equipment and materials to build large cosmic test bench

(2x2m2) ordered and partially delivered; waiting for scintillators from IHEP Protvino

o long delay due to involvement of university safety (isobutane gas, HV …) and building service (gas safety cabinets, air conditioned hut, fences …)

Lab should be operational by the summer

Manpower

February 5, 2010 RPC Upscope Meeting 9

Manpower available for chamber assembly and testing, assuming the project starts this year and the assembly is done in Belgium

VUB: o 2.5 FTE technicianso 1 FTE engineero 1 Physicist

UGent :o 2 FTE technicianso 1 FTE technician to be hiredo ~1 FTE PhD studentso 0.5 FTE Physicists

UCL :o 1.5 FTE technicianso 1 technician for transport of material and detectors

(Belgium-CERN)o 1-2 PhD studentso 1 Physicist

Budget

February 5, 2010 RPC Upscope Meeting 10

Expected Belgian contribution to the RPC upscope project : 800 kCHF

o Belgian Cost to Completion 3 attributed to RPC upscope : 456 kCHF

o “Big Science” projects in Belgium : 225 kCHF

o UGent CMS entry fee attributed to RPC (?) : 150 kCHF

o Additional small contributions from institutional research projects funded by the FWO-Flanders

Concluding Remarks

February 5, 2010 RPC Upscope Meeting 11

o The participating Belgian groups are ready to take up the responsibility to assemble a large part of the new chambers for the RPC upscope

o Manpower is available to do the assembly locally; infrastructure should be ready by the summer

o Belgian financial contribution to the upscope project seems secured

o Chamber assembly should start asap to avoid losing essential people

o If requested, the number of detector assembly sites can be reduced, e.g. limited to UGent and UCL

o Sending Belgian technical manpower to CERN for longer periods for chamber assembly could be a problem

o Having a (spare ?) chamber assembly line in Belgium will be beneficial for training new people for the commissioning/maintenance of the RPC system
