Modification notes: 30 Jan 08: 1st version Sorina05 Feb 08: 2nd draft Aldo06 Feb 08 : modified by Kerem Added Items to the commissioning and RADDAM sectionsmodified feb.22 08 by Ianos Added Items to the "complete installation" section, and made separate section for HF+ and HF-. Also added misc. to do section.

HF task assignements• HF ± Services:

– N2 final assembly (panels, flowmeters) [Ianos, Sasha]– Source tubing and drivers installation [Ianos, Olga]– Rad Monitors installation [MSU - Ershov]– C-rails and ROBox extractor [TTU - Sorina]– Laser fibers [Sorina, Vasken]– RADDAM implementation [UoI – JeanPierre]

• HF - commissioning [Alexi, Kerem]– Compare data samples [Salim, Dmitry]– HF - commissioning team:

Aldo, Alexi, Kerem, Dmitry, Numan, Salim, Sorina

+ Ianos, Olga, German, Serguei, Sasha, Vitali, … + Lisa, Ferhat, Efe, Jean-Pierre, Arjan, Richard(s)

[Report to /(advice by) Andris, Pawel,…]

HF- commissioning status• Pedestals:

– Initially 4 channels bad

– black cables (ROBOX’s – QIE) cause – 3 repaired/1 replaced

- Now all 864 pedestals OK

• Mapping/cabling: – found mismatch between HF- e-map and HF- cabling (20-01-08)

– temporary cabling change, then map change (cabling restored)

– still debating…,

However:

• Pedestal comparison (B186 vs UX5) ≈OK!• HV switched on:

– progressively (possible light leaks) @ 1100 V

• LED timed in:– Found 4/864 missing LED channels (investigating…)

Pedestal comparison betwen B186 and UX5HFminus, ROBOX: 1,2,3

Plots from Dima Vishnevskiy: Blue squares – B186 measurements, green triangles -- UX5 measurements, run 34826

Missing one channel

Problematic channels fixed (cable problem)

• Improve timing & pedestal subtraction

• No LED from 4 channels • Comparison with B186

ASAP

Sourcing in garage:preparations

• First meeting with RP (Pawel+Vitali+Aldo)• Preparing sourcing procedures• Installation safety controlled doors• Establish interlock systems• RP rough estimate of dose rate:

– source: Co-60 185 MBq - shielding: 20cm plexi, 2 cm Fe, 4cm Pb

– distance: – at contact ~25 µSv/h – at 40 cm ~4 µSv/h

(sounds good, but no distance given from Pb to the garage doors...) • Reminder: - Before the first run, non-designated area, people don't

wear dosimeters, the ambiant dose rate should be below 0.5 µSv/h • - After the first run, at least supervised area, people will have to

wear a valid dosimeter, the ambiant dose rate should remain below 3 µSv/h

Other Items

• RAD Monitors ready to install

• RADDAM : Main issue transmission fibers;

• BSC ready for installation?

• CASTOR/TOTEM infrastructures?

HF - : risky situation noticed…

Cables in standard chain Cables loose on bottom of trench

Rad Monitors

CASTOR/TOTEM

infrastructures

• Support table • Gas rack

HF in UXC55

Coming OUT and UP! When?

Backup?

The HF group is rather chaotic, but in general well-intentioned, and heading in the right direction…
