RRB scrutiny Report: Muons

Internal scrutiny group for RRB report

• Internal scrutiny group composition– J. Shank, G. Mikenberg, F. Taylor, H. Kroha, M.

Livan, J.Huth– Report on

– 2012 financial activity– Current situation for 2013– New forecast for the period 2014-2018.

Expenditures in 2011

The large carry over from 2011 (250.1 KCHF) has covered for the larger expenses in 2012 due to past commitments and to the larger running period and preparation works.

2012 main driving costs– Mechanics: 137.1 kCHF

• this includes mechanical parts and PC boards for the feet trigger (53 kCHF), transports, and also material for RPC gas distribution (15 kCHF). Mechanical expenditures were also due to the finalization of the EE chambers mechanical structures (20 kCHF). In addition, 14.8 kCHF has been spent on mechanical parts coming from the CERN Store. Two ATLAS agreements, one aimed at the repair of the RPC gas leaks (15 kCHF) and the other for the development of an alignment system to include the BEE chambers in the End Cap alignment (15 kCHF) has been signed in 2012.

• The larger expenditures were due mainly to the feet trigger partsand the RPC gas distributions parts that were in the open commitments of last year

– Electronics : 218.3 kCHF • The main cost drivers were the provision of the new mainframes

for the power system (105 kCHF) and the provision of cables for the elevator chambers (20 kCHF). About 20 kCHF were used for testing materials for EE chambers. In addition the maintenance of the CAEN Power supply system (39 kCHF) and E-pool rentals for about 21 kCHF were also important expenditures.

EE Installation and commissioning

2012 : Installation and commissioning of 5 EEL sectors Side C 8 EES sectors on side C+ 1 EEL Sector on Side A

2013:Installation and commissioning of 4 EEL sectors side A8 EES sectors on side A

The Muon Spectormeter is now completed as designed in the original muon TDR

2012 main driving costs– Hired manpower: 392 kCHF

• Spent for maintenance of the detectors including gas systems, front end electronics, DCS, DAQ and alignment systems. A major cost driver in this item was the commissioning of the EE chambers that have been installed on side C of the detector. The larger expenditures as compared to the plan is due to the extension of the running period in 2012 and the starting of the activities for the shut down specially in the DCS and in the RPC areas.

– DCS and Controls: 89.8 kCHF• The main cost drivers were the replacing of DCS standard Servers

(27 kCHF), the replacement of the PCs used in the satellite control room (7 kCHF), the purchase of new CAN power supplies (6.4 kCHF) and the cost of the modification of the firmware of CAEN boards (8 kCHF). Moreover about 40 kCHF were accounted in 2012 for work on DCS done during 2011.

Expenditures in 2012 and expectations up to 2018

No changes with respect to the total budget profile presented last year

2013 situation• No financial issues foreseen for this year.

– Mechanical expenses will be largely reduced to previous year (EE structures completed) 26 kCHF will be shortly paid for the purchase of Gas Jumpers for the EO MDT (received few days ago).

– Cost for maintenance of CAEN circuits decreased wrt 2012, During this year we will still need to buy new modules for the power system to improve the monitoring and control of the HV/LV system, to replenish the spare stock and to power the chambers in the elevator holes.

2013 situation

– Manpower expenditures in line with the forecasts (even a bit below due to the preparation work done in 2012) and mainly concentrated on maintenance of RPC HV/LV system, RPC Gas system (see next slide) , EE installation and commissioning, DCS renewal of Computers and operating system.

– Procurement of DCS standard servers for TGC and RPC will be done during the remaining of the year (or split between this year and next year)

– Procurement of the alignment PC and interface card for the barrel to be done during this year (or split between this year and next year)

RPC gas repairs

• As already reported, RPC gas inlet are fragile and show different types of failures (photos).

• We have developed techniques to fix all these failures

• Part of the manpower expenditures for 2013 and 2014 will be devoted to this important task.

2014 expected budget• For the year 2014 the foreseen budget for M&O-B is 570 KCHF (80

KCHF less than in 2013) – Mechanics: 60 KCHF

• Maintenance of the gas systems (e.g.: re placement of RPC gas inlets, periodic re placement of filters in the gas distribution)

– Stable expenditures on cooling system: 15 KCHF• Replacements of the fan trays for all the Power supplies in USA15 is foreseen in 2014.

– Cost for maintenance of electronics will be lower by 50 KCHF: 160 KCHF– DCS/DSS and Alignment system cost : 30 KCHF

• The DCS and Alignment PCs bought in 2013 will be installed in the experiment.– Communications: 5 kCHF– Technical manpower lowered compared to 2013 by 50 KCHF: 300 KCHF

• Shut down year, may activities ongoing on top of the standard detector maintenance:– Completion of installation and commissioning of trigger in the feet region– Re-installation of Small Wheel C– Deployment of new trigger firmware in the end cap to allow to use the Small wheel

TGC information.– Re-commissioning of the full muon system, cosmic ray runs etc.

2015 and 2016 expected Budget• In 2015 the LHC is foreseen to be running continuously and the

requested budget is 570 kCHF– The main changes compared to the previous year are an increase on the cost of the

maintenance of electronics and a decrease of the needs of technical manpower.

• For years 2016 and 2017-2018, the foreseen budgets for M&O-B are 800 KCHF (2016) and 830 KCHF (2017-2018)– Main driver for the increase in budget is the start of the commissioning

activities for the new detectors foreseen for the muon upgrade (New Small Wheel).

– Based on the experience of the previous commissioning phases we foresee • expenditures for mechanical parts at the level of 120 KCHF per year• Expenditures on technical manpower at the level of 330 KCHF per year except

in 2016 (300 KCHF) since the commissioning will probably not start at the beginning of the year.

• We foresee the need of renewal of the CAEN/WIENER power system that we will spread in those three years which entails an increase on electronics expenditures of about 100 KCHF per year.
