1. Quotes from the latest technical news as posted by R. Catherall:
· The full controls of the FE7 are being tested and will be finished this Thursday.
· The FE will be re-started this Friday and, after testing the FC with a W Surface ion source, a plasma ion source will be installed for further testing.
· The targets have been removed from the target area to ISR using a transport container.
· The GPS extraction electrode was removed on Monday morning and conditioned.
· All GPS cabling has been decoupled. The vacuum group are currently in the process of decoupling all umbilical vacuum connections as well as the FE from the separator beam line. The BTY vacuum line section in the path of the Front Ends has been removed.
· The new picoameters are currently being installed with connections to the network foreseen for next week. There is a small delay in the cabling due to a lack of short cables.
· The REX plc and cabling installation is finished but the software is not yet installed.
· Maintenance work on the cameras in the target area is finished. Two tubes have been exchanged.
· All overhead crane inspections have been done.
· Siren tests in the hall have been completed successfully.
· The compressed air of the GPS Frontend has been cut prior to removal.
· The work on the REXTRAP controls is progressing well.
· A lot of the vacuum controls equipment and cables for REX has now been removed ready for the installation of the new vacuum controls.
· The modification of the IHS cooling water station is now finished.
· B. Marsh et al. are currently making provisions for the modification of the laser beam path in the HRS separator zone. This is in anticipation of a proposed experiment involving laser pumping in the RFQ Cooler.
2. News from the INTC technical advisory committee (TAC):
· The committee discussed all documents submitted to the upcoming INTC. The feedback of TAC members was positive and it will continue its work before each INTC. Some points were identified for several proposals (mainly concerning the feasibility of providing the requested yields).
3. Safety:
· The safety authorities maintain their opinion and recommendation that the SSP lab in building 275 should be transferred in the radio-protection area of ISOLDE, most likely in building 115. The latter currently does not provide the space needed for the corresponding equipment. An extension is being considered.
· In order to accommodate acquisition rooms for HIE-ISOLDE, building 507 might need to be extended as well. On the other, hand b. 507 is not in the best shape and it is a relevant question how to take care of it in the future.
· With the transfer of the SSP lab b. 275 will no longer be associated with radiation hazards and the plan is to convert it to an office building to house the workshop and technical staff of ISOLDE.
· There is an idea to convert b. 570 into an office building for the ISOLDE physicists. This has the advantage to be closer to the experimental hall, but one concern is that it might not provide adequate space. This is still in the phase of an idea in discussion.
4. A.O.B:
· “The ISOLDE facility”by Alexander Herlert was published in Nuclear Physics News.
· The BE-DSO, guided by the ISOLDE coordinator and TSO, inspected the safety condition of ISOLDE. His evaluation was very positive.
· According to the PH-DSO Christopher Griggs ISOLDE is leading the way to safety at CERN. This statement is in conjunction with the coordinated efforts to establish a comprehensive documentation for experiments at CERN in which respect seminars and discussions with the ISOLDE physics group appear to be rather useful.
· Magda proposed a cleanup of the ISOLDE hall on Feb. 7, starting at 13:30.
· Jens Roder (Technische Universitat Braunschweig) presented: “Digital PAC-Spectroscopy: Development and Experiments”
· There will be no group meeting next week due to the absence of many people who will be at the SPIRAL2 week. The following week due to the INTC schedule the group meeting will be held on Tuesday Feb. 1 at 15:00. It will be followed by a seminar by Paul-Henri Heenen. Note the unusual day and time.
