Work on HF platform –z end

• Installation work ongoing in garage position We need some 3-4 days of notice to stop and prepare to move out of garage

• Foreseen date of move out of garage:– either 1/8 if no end cap e-cal installation on –z end– or 18/8 with cap e-cal installation on –z end

• Work in “floor position”• Work in height of 2 risers• Work in beam height

Garage position

• We will continue to work up to HF is moved out of the garage

• Castor:– 1. test of installation tools on 15/7. Some (small) mods on feet's

needed. Next test on Monday 28/7– Cabling will finish by 25/7– Installation of cable chain to be finished by 25/7/2008– 1 Marathon crate to be installed

• BCM– T2 rails need shimming (geometry of table pretty bad) by 21/7– Cabling finished by 25/7

Garage position (cont’d)

• TOTEM T1– Install rack’s (if possible in garage)– Equip rack’s with marathons

• Totem T2– Install marathon 17/7– Cabling and piping by 25/7– Modify 5 vertical pipes (collision with rotative shielding) 25/7– Install detector (if possible) 2 days

• Services– Connect cooling to racks (latest in week 28/7)– Install Lauda on HF and connect to

HF close to End cap on the Floor

• We need HF open for the ease of access.• Day 1 : Install T2 (if not yet done) mechanics

• Day 2 : Install Castor mechanics (crane close to beam pipe )

• Day 3 : Cabling of Castor and T2 (in parallel)• BCM needs > 1 day of access (in parallel)• Test of closure procedure??• Install cables and pipes on YE4 for T1 (5 days)

HF lifted up 2 risers

HF lifted up 2 risers• Table in maintenance position• Collar open • Access to both sides (difficult to cross from near to

far side)• Install PT100 temp probes on beam pipe• T1 installation

– Close HF– Finalize cable and piping on YE4 (if needed)– Install truss (1 day)– Install detector (1 day)– Connect, test and de-connect(1day)– Open HF

• BCM, Castor and T2 need access

HF in Beam Height

• Final connection of T1 (1/2 day)• All detectors will need access (install bridge?)• Closing of detector and shielding…3 days??
