The in es iga ion o he undamen al pa icle, he basic cons i uen

The CERN ac i i y is egula ed by an al e na ion o wo pe iods:

F om he beginning o he LHC ope a ion, in 2008, CERN has had

The p ojec o he es bench, om he concep ual o he de ailed

The wo k has ca ied ou in collabo a ion wi h se e al g oups

and manu ac u e.
The main phases o he p ojec can be summa ized in he ollowing

81
• Analysis o he echnical speci ica ion and a
consequen ly ca e ul ma e ial choice;
• Concep ual design wi h Au odesk In en o ;
• Nume ical s udy, based on he Fini e Elemen Me hod,
o he implemen a ion o he p oblem in ANSYS;
• Selec ion o all he equipmen used;
• Discussion wi h he supplie s o he bes op ions;
• De ailed design o manu ac u e;
• P epa ing he echnical d awings o manu ac u e;
• In con ac wi h he echnical employees o he p ope

The inal p oposal o his p ojec is a hyd aulic es bench based on

The ci cui has a o al olume o 96 L, dis ibu ed in 50 L he ion

In he u u e, i could be a good idea o ins all a hea exchange o

subsec ions bellow. I any doub a ises du ing he usage o he Tes
bench, he pe son in cha ge o he Tes bench a CERN mus be
con ac ed.
1. Connec he chambe o he Tes bench.
2. Ins all he a ge pieces inside he chambe .
3. Open he al es V1, V2, V3, V4, V6, V7, VR1, VR2 and VR3
and close V5
4. Connec and/o u n on he cooling ap wa e .
5. Fill he ci cui wi h ap wa e un il 3-4 ba .
6. Connec he powe cable.
7. Tu n on he es bench.
8. Run he p og am.
6.1.3. Connec he chambe
The chambe mus be placed in posi ion on he Tes bench be o e
