B2 B1 B1B2 B V. Kain, R. Alemany ALICE SHOTS ON TED = 20 hours (TDI closed to avoid forward detectors trips) LHCb SHOTS ON TED = 18 hours Note: If 100% efficiency is assumed BLM to COLLIMATOR MAPPING  If possible will be done during aperture measurements

Total beam intensity and RP Assuming 100% efficiency and two extractions per minute of p+ (or p+ for trajectory stability) Total intensity per activity Total intensity per TED and for the whole weekend: TOT INT B1 = p+ TOT INT B2 = p+ 4.8E E+13 V. Kain, R. Alemany

In October 2004 we performed a similar test as it is planned this year for the TI2 and TI8*. With similar total beam intensities on TED. Prompt radiation: Point 2 and 8 and neighboring tunnel areas have to be closed during test. Relevant RAMSES radiation monitoring will be operational during the test. Residual radiation after test: TI tunnels: Area around TEDs will show dose rate levels being clearly above current “Supervised Radiation Area” classification. LHC tunnel: Areas in R22 and R88 located parallel to TED positions in the TI tunnels will show elevated dose rate levels. However, most probably there will be no need to change locally the current classification (Supervised Radiation Area). Prior access radiation survey will be conducted.  no access restrictions are expected after test in the LHC tunnel. *Dedicated RP report available: H. Vincke, D. Forkel-Wirth, N.

Other topics When changing the beam intensity from PILOT to NOMINAL bunches and vice versa, we have to close the TIx_SETUP handshake and start it again. Put the new intensity in page 1 and call the experiment control room. If a patrol drops in ALICE or LHCb: 1 st call the experiment control room and the run coordinator. To broadcast the ON LINE development of the plan we will use the LHC Coordination page: webtools/vistar/vistars.php?usr=LHCCOORD V. Kain, R. Alemany
