TRANSCRIPT
Outlook• Production of the 12 DPs (220m Stations) • Installation of the DPs in the LHC Tunnel• Status of the RP Systems/Services• Resources • Production of DPs for the 147m Stations
TOTEM Roman Pots Detectors
G. Ruggiero (PH/TOT) LHCC minireview – 21 September 2009
Production up to Detector Package 12
The production for other pots is ongoing…
The RP Stations at 220m sect 56 (April 09) and 45 (August 09) are fully installed.
Production schedule presented in the previous meeting strictly respected !!!
Production completed end of June !!!
Detector Packages Installation (July 2009)• All the pots formerly installed have been extracted for final inspection
together with the last produced pots.• The insertion of all the 12 Detector Packages has been completed beginning
August.

• All efforts concentrated on the stations at 220m• Most of the work limited by access to the tunnel (these
activities almost completed).
• Unforeseen two weeks of no cooling has affected the advancement of the commissioning of the RPs
People (physicists, engineers, technicians, students…) helping in this phase of the project.
Not all 100%!!!

(Table updated continuously)
The production for the pots at 147m is continuing. Nevertheless, at this stage is hard to produce a reliable planning for these items
