Following the LHCC recommendation to carry out beam channeling experiments using bent crystals in the LHC, it is proposed to install the needed equipment in IR7. Two crystals are needed for horizontal and vertical collimation, respectively. Each crystal is mounted on an in-vacuum goniometer. Two in-vacuum Cherenkov detectors are designed to measure the system performance. During LS1 it is proposed to reserve the space for all the devices, to prepare the needed infrastructures and to install the two goniometers containing the crystals.

Installation of Cryogenic Beam Loss Monitors on MBs in IR5 and IR7

M. Sapinski The current Beam Loss Monitor (BLM) detectors are installed on the outside of the vacuum vessels of the superconducting magnets. In order to improve their sensitivity to beam losses and capability to detect quench-provoking loss levels it is proposed to install new BLMs inside magnets during LS2 and LS3. The installation proposed here for LS1 is a part of a study to select and test the optimal cryogenic detectors. The ECR describes the proposed location of the new detectors on the cold mass of dipole magnets in dispersion suppressors of IR5 and IR7.

To gain in angular resolution and therefore in t-resolution, the proposal is to move the ATLAS/ALFA B stations (B7L1 and B7R1) by 4m away from the IP. We would take advantage from the fact that the stations need anyway to go to surface for upgrade activities (see ECR LHC-XRP-EC-0008) and from the fact that the DQR’s (the stations are located in between two DQR’s) will be taken out for maintenance.

TOTEM proposes to move these stations to 210 m (between Q5 and Q6) on both sides of IP5, so that after LS1 the TOTEM setup will contain a new 210 m station with a near and far unit in addition to the existing 220m station. The new 210 m far unit will be rotated by 8 ° around the axis of the beam.

Re-Alignment of BPMWB close to D2 before Recombination Areas at Points 1 and 5 of the LHC

E. Page The original installation did not foresee an appropriate distance between centres for the BPMWB between D2 and TAN. The BPMWB axes are not centred on the beam axis, whereas upstream and downstream modules are. Therefore, vacuum modules (bellows) have to accommodate a rather large radial offset, outside bellows specifications. This ECR proposes a slightly different position for the BPMs, in order to correct these constraints

Upgrade of the Matching Monitor BTVM.7L3.B2 in LSS3 of the LHC

S. Burger The goal of these new instruments is to measure, on a turn by turn mode, the transverse beam profile during the first turns after the injection in order to optimize betatron and dispersion mismatch (injection studies). There are 4 BTVMs installed around the LHC (2 in point 3 and 2 in point 4). These new installations will consist of replacing the standard BTV optics and detectors with new optical lines, detectors and acquisition systems. This ECR treats the BTVM.7L3.B2 which has an environment slightly different than the 3 other BTVMs.

Installation of infrastructure and services in the forward region of IR1 and IR5 (at ~225m from IP’s) for a possible installation of physics-debris collimators (TCL) on the IP-side of Q6 is proposed. This modification will ensure the possibility to have a quick installation of collimators if required. It involves collimator supports, water-cooling, cabling and the displacement of the DQR cooling stations in IR5.

New Cable Infrastructure in LHC-Point 3

J. Crespo Bisquert, J.-C. Guillaume, R. Malinowski

It is proposed to install new control cable trays in IR3 on the transport side of the tunnel due to difficult access to the current cable trays. The new infrastructure will allow reducing the time spent by the workers in high radiation areas during the cable installation, in agreement with the ALARA principles. The designed capacity of the new cable trays will be sufficient to back-up the total number of control cables already installed in IR3 (machine side).

Safe Room Implementation in UL557

A. L. Perrot As described in a previous ECR (LHC-LJ-EC-0026), relocation of equipment sensitive to radiation, in particular to so-called Single Event Effects (SEE), from UJ56 to UL557 will be carried out during the Long Shutdown 1 (LS1). Part of the equipment to be relocated is installed in the UJ56 safe room. It is proposed to relocate this equipment in UL557 in a new safe room. This ECR documents the design of this new safe room.

Protection of Equipment located in UX45

A. L. Perrot Failures on the cryogenics equipment located in the part of the UX45 closest to the tunnel were observed during 2012. Some of these failures have driven significant downtimes during the LHC operation. End of May 2013 it was approved by the LHC Shutdown Committee to relocate the sensitive equipment outside the UX45 critical area into the US45 and the adjacent UL44/46, where the amount of radiation is reduced.

LACS/LASS Top of Pit (ToP) Maintenance Doors

R. Nunes The purpose of this modification is to increase availability of the LHC Access points during the necessary maintenance activities. The maintenance of the LHC Access Control System (LACS) and LHC Access Safety System (LASS) elements is heavily restricted by factors of safety and availability. During the run of the accelerator, maintenance actions cannot be performed because any opening of the external envelope doors would interlock the beam. During accelerator stop, the LACS/LASS system must remain available to access the underground facilities, thus constraining both access and scheduling of maintenance. This proposal aims to improve this situation by allowing maintenance during Beam Mode.

Installation of Cryogenic Beam Loss Monitors on MBs in IR5 and IR7

M. Sapinski The current Beam Loss Monitor (BLM) detectors are installed on the outside of the vacuum vessels of the superconducting magnets. In order to improve their sensitivity to beam losses and capability to detect quench-provoking loss levels it is proposed to install new BLMs inside magnets during LS2 and LS3. The installation proposed here for LS1 is a part of a study to select and test the optimal cryogenic detectors. The ECR describes the proposed location of the new detectors on the cold mass of dipole magnets in dispersion suppressors of IR5 and IR7.

The LHC BSRT systems are designed for transverse and longitudinal profile monitoring using synchrotron radiation [1,2]. The replacement of the BSRT-A tank by a BTVSI tank is planned in order to move the BSRT calibration line out of the optical table. This is expected to improve the quality and reliability of the calibration (alignment, magnification and focusing). In addition, the space on the table now occupied by the entire calibration line will be used to test the possible BSRT system upgrades such as interferometry and low wavelength optics. For the moment, the change is requested for the Beam 1 system only (LHC cell 5R4).

Following the LHCC recommendation to carry out beam channeling experiments using bent crystals in the LHC, it is proposed to install the needed equipment in IR7. Two crystals are needed for horizontal and vertical collimation, respectively. Each crystal is mounted on an in-vacuum goniometer. Two in-vacuum Cherenkov detectors are designed to measure the system performance. During LS1 it is proposed to reserve the space for all the devices, to prepare the needed infrastructures and to install the two goniometers containing the crystals.
