Status of the experimental area4

Status after the last technical stop (TS 4-8/7/2011):Status July 2011 & remaining work 2011

3 base tables installed and aligned to the beam

All signal cables pulled from TNC to TJ7 and from TJ7 to control room (installation rack in TJ7 and connection cables to tables planned for next TS)

Table cooling circuit installed (connection to tables and pressure test planned for next TS)

Also to be done in the next TS: quick connector on gas line opposite tables + completion gas line from TJ7 to surface

Shut-down work6 Activities for 2011-2012 shut-down:

Cabling of tables 1 and 3 from table to control room Installation of power line (4kV) from table 2 to surface Additional remote handling tests if needed Exchange of entrance window of TED-style beam dump

(remote handling of upstream collimator, shielding &TED) Remote handling of 2011 test tables from cool-down area

to surface (after RP green light) ??? Disposal of former-T9 copper blocks currently stored

in sarcophagus in downstream T9 (only if RP green light, possibly delayed until 2013-2014 shut-down)

Life cycle of test table8 Operation

Reminder: Test objects must be contained, cable feed-throughs and portholes must be tight

Installation of table is 100% remoteEach access to TNC must be duly justified. They must be requested before the test table installation.

After the beam test, the test table will be moved remotely to the downstream cool-down zone for a cool-down period defined by the radioprotection team.

After the cool-down period, the object will be transported to the surface and brought to an adapted (CERN-RP) lab for dismantling. HiRadMat project recovers the mobile table, the user is responsible for treatment of the test object (disassembly, analysis, disposal).
