ATLAS rental fees

Situation October 2002 27 ATLAS budget codes are used Total monthly rental fees:

– 33600 ChF per month i.e 403 kChF per year– 4.35 MChF of rented equipment– Annual rental fee ~ 10% of the equipment cost

Most important are for test beam activities– e.g. Liquid Argon 69.6 kChF/year

Or for DAQ– 99.2 kChF/year

Some statistics

In average 59% of the equipment has been continuously rent for more than 4.5 years DAQ is special because of the high rental fees of CPUs

Remarks

Most of the equipment is rent (and used) for a long period of time

It does not make sense to use a service optimised for short term loans– Full support from the pool has a cost: administration,

availability of spares, … There will be needs for new equipment in the future

– Lab equipment for tests and commissioning

EPTAB August 2003 5

Ph. Farthouat

Proposal (1)

Transfer the ownership of equipment which has been continuously rented since January 98– ATLAS financially responsible for maintenance and spares

» i.e. pool will charge ATLAS for each repair

– If not used, back to the pool– ATLAS will save a bit a money– Pool will save administrative cost and reduce its stock

EPTAB August 2003 6

Ph. Farthouat

Proposal (2)

Transform the rental scheme in a “leasing” for the equipment rented after Jan 98 but that we think we will keep for long time– Again ATLAS must be financially responsible for spares

and maintenance– ATLAS will save some money in the long term– Pool will have less worries about spares etc…

Proposal (3)

Pool rental reserved for short period of time and high end equipment– May be higher cost

Future needs

Georges Schuler circulated a questionnaire to each project leadera) Overall satisfaction with poolb) What will happen after 2004?c) Specific needs for high end equipmentd) Will NIM and CAMAC modules still be needed?e) NIM and CAMAC functionalities in VME?

Got one formal answer from a group with no CERN involvmenta) Difficult to find needed specialised equipmentb) Very little usec) Very desirable; otherwise equipment from home institutesd) Noe) Yes but no guaranty to rent it...

What will happen after 2004?

No test beam in 2005 Not yet clear what will happen after but

– Installation in the pit starts end of this year » Calorimeters installed in 2004» Inner tracker integration on the surface starts also in 2004

– More interest in having cosmic runs in the pit than beam test– Very likely a lot of equipment will be given back to the pool

High end instrumentation needed– Could come from the pool

Infrastructure equipment also needed– Crates,– ...

Summary

ATLAS is a large user of the pool– 400 kChF per year since many years

Some proposals were made in order to– Save ATLAS money– Reduce pool volume

Needs after 2004 not yet clear but – Very likely a lot of test beam equipment will come back– Interest in high end instrumentation
