AUTOTUNE 8.1 PRESENT INSTALL

Catherall then briefly summarises the RILIS equipment upgrades during the end of year shutdown as well as the developments that are planned before the start of physics in April 2018. Chrysalidis (PhD Student), with support given by PNPI and the LARISSA group in Mainz. The proposal is being refined before it is presented to the PS-CSAP (PS-Complex Safety Advisory Panel) for approval. This would mean that Users, who would be informed as far in advance as possible, can still enter the hall but only for a limited amount of time and they must avoid hotspots. A working group has outlined a proposal for future high intensity operation that would change the ISOLDE hall from вЂњSimple controlled areaвЂќ to вЂњLimited Stay controlled AreaвЂќ for the duration of the experiment. A proposal to continue running with the hall in lock down was rejected by CERN so the run was completed at a proton intensity of 0.2 в™љ. After several radiation alarms in the hall were activated, a radiation survey found a number of hotspots. The committee is reminded of the radiation issues that occurred during the 94Rb run that took place in September 2017.

It is planned to install a second new HT power supply and modulator during the 2021/2022 end of year shutdown. GPS and REX power converters are being replaced and a new 60kV HT power supply and modulator, mainly for use with the HRS, is being installed. Catherall begins by summarising the power supply consolidation work that is taking place in the ISOLDE hall. YETS (Year End Technical Stop) Activities at ISOLDE вЂ“ R. Siesling and his colleagues for the work completed so far and for keeping to the schedule to allow physics to start on time.Д¤.

The planning for the remaining activities of Phase 2 are presented and the committee informed that the start of HIE-ISOLDE physics is still foreseen for July 9 th 2018.Д«. It is clarified that the operation of ISS is carried out by the ISS collaboration but the responsibility of its installation was taken into the HIE-ISOLDE project. Siesling briefly summarises the REX RF maintenance and repair that is taking place and on track as well as the ISS installation status at XT02. It has become clear to the cryogenics group that HIE-ISOLDE Phase 3 will not only require consolidation of the cryoplant but also of the CDS the cost of which would be borne by CRIOTEC.Д®. The repair of the Cryogenics Distribution System by CRIOTEC is also underway and on schedule. The committee is informed that maintenance of the cryoplant is ongoing and should be ready for cool down by March 23rd. However, due to sufficient margin in the planning, the milestones for cryo cooldown, CM4 and beam commissioning can be kept unchanged. This is because other CM4 top-plate work cannot begin until the cryogenic work has been finished. While the starting date of vacuum installation work being moved from 29 th January to 19 th February does not affect other CM4 activities, they are affected by the starting date of cryogenic work being delayed until 12 th February. The cryomodule is installed and aligned but both vacuum and cryogenic installation work have been delayed due the unavailability of the required manpower who are working on other machines at CERN. The installation work that has taken place in the tunnel since the arrival of CM4 is summarised and the status of the CM4 installation is presented.

Siesling explains which installation work took place during December 2017 and January this year in order to prepare for the installation of the fourth cryomodule (CM4), which was successfully transported from SM18 on January 23 rd. The main activities of Phase 2b of the HIE-ISOLDE project are summarised. Status of the HIE-ISOLDE installation and shut down work вЂ“ E. The minutes from the previous meeting are approved.ДЈ. Approval of the Minutes of the last meeting of November 7th, 2017 Blank, opens the meeting and excuses the committee members who are unable to attend the meeting.Дў.
