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

Status of the experimental area5
Status after the last technical stop (TS 4-8/7/2011):Status July 2011 & remaining work 2011
3 supports for test tables installed in cool-down zone
Extensive handling tests done with movable table (remote tests planned for next TS, when final camera system installed)

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).

1. From lab to test zone (non-radioactive object) Surface lab: overhead crane to trailer Trailer: from BA7 material lift TJ7 TJ7: transfer to overhead crane Remote with crane: TJ7 test zone in TNC
Lab to test zone
Custom-made trailer
Handling of test tables15 Cool-down zone
Cool-down zone for test tables with test objects Downstream in TNC, within reach of crane 3 places (supports) foreseen for 2011, 5 more for 2012
Downstream end of TNC
Test table supports 100% Aluminium Mechanical guides for remote
installation (also remote dismantling) Handling exercises in tunnel planned
Handling of test tables16 Test zone to cool-down zone
2. From test zone to cool-down zone (radioactive object) Remote with crane: TJ7 cool-down zone in TNC Remote with crane: place on cool-down zone supports
Handling of test tables17 Cool-down zone to surface
3. From cool-down zone to surface (radioactive object) Remote, with crane: cool-down zone in TNC TJ7 Remote, with crane: place on trailer Manually, protected by distance (and shielding if needed):
TJ7 material lift surface Manually and in truck with container (and shielding if needed):
surface CERN radioactive lab for disassembly When needed, followed by waste disposal (CERN) If dose rate negligible empty mobile table can be re-used
