Machine related activities in the experimental hall 10mSpeakers: Erwin Siesling (CERN), Simon Mataguez (CERN)
Platform EPC:
- AC cabling and distribution finished: As built to be verified with the existing CATIA model in the frame of the zonage of the overhead crane.
- HT cables all reconnected and tests of the cables between patch panels and machine ongoing: Meeting held with WSS (Rustan Calming), contractor and RP (Nadine) on access to the separator zones. Cables numbering will be renewed / added.
- Support old/excisting vertical cable tray in place. Apart from the removal of the scaffolding the floor is ready for adaptation of the old false floor. Proposal Jean-Pierre Billon-Grand.
Fiber installation work:
- fiber duct installation along the Saleve wall and above RILIS barrack and GPS bunker has been done (31 March Nenad Simic & contractor) in coordination with green cage removal.
REX/HIE ISOLDE preparations CM1 transport:
- CM1 radiological aspects: List of isotopes with long live daughters were identified (Fabio). Data on duration, intensities and (estimated losses) has been compiled (Miguel). BAsed on the nuclide inventory provided by Fabio the transport will be exempted. To confirm this 2 last points of info are to be transmitted to Philippe Bertreix: - dose rate at contact (to be measured when CM1 is out of the tunnel), - confirmation there is no contamination accessible (RP, Erwin)
Info tunnel roof opening & transport CM1 -> SM18:
- PR214 verification done. Confirmation that the PUMA modification on the overhead crane PR214 will not hamper the handling of CM1. We will proceed with the schedule as planned.
The modification/displacement of the PUMA drum and cupboard will be carried out after the CM1 handling and transport, as of Friday 24th April. Verification proposed change before with integration (point for the ICL, Filippo Cappaletti, Vincent Barozier). Laser tables removal in week 18, after modification/removal PUMA drum, etc. (29/30 April). - This Week 16 (13-17 April):
Tunnel has been opened Monday 13/04 (ahead of schedule - due to transport availability). (Thanks to the VITO team and others for clearing the Jura side HIE ISOLDE wall). Door to the tunnel roof closed by key (RF room) no access apart from HE/Tranport team.
CM1 out of tunnel to the handling zone Thursday 16/04 - Attention: craning work and handling equipment in the hall.
CM1 will be standing from 16 - 23 April in the handling zone next to the yellow RP buffer zone: vibration and inclination sensors + wrapping for transport - Week 17 (20- 24 April):
Transport CM1 from ISOLDE 170 to SM18 - special transport (truck & trailer) arriving 23 April (confirmed). Heavy use of the overhead crane during handling in the 170 hall (CM1 onto pendulum/trailer).
SAS and handling zone to be empty (users will be informed). Parking to be empty (IBDRS project has been informed) - Thursday 23rd April difficult traffic circulation around ISOLDE with the Rte Einstein closed (CM1 transport) and Rte Democrite closed (crane). Exeptionally Rte Rutherford will be opened - tbc with the 133 refurbishment project.
Perturbations to be expected end of the morning at the border when the road will be closed for ~1 hr to pass with the truck. - RILIS planning kept in the loop (Carlotta, Laura), ISOLTRAP planning kept in the loop (Arthur Jaries) - ISOLTRAP dewars craning: mornings of Fri 17/04 (LN2), We 22/04 (LHe) and Fri 24/04 (LN2) in line with the CM1 handling planning.
Planning REX/HIE: 170 REX HIE planning | Document 3383102 (v.1)
Vacuum pumping / ventilation:
- For the investigation at EBIS to find an assumed leak its vacuum system will need to be restarted (Guillermo): Ventilation systems operational as of 27th April confirmed (requirement for the restart of the primary pumps)
Work in he 170 HT room:
- Julien Parra-Lopez: Replacement of the GPS and HRS target heating power supplies. New equipment has been moved up to HT room and installation is ongoing.
Beamlines:
- RC6 EN/EL AC cabling work has finished now follwed by signal cabling. The contractors have been informed and are aware of the CM1 tunnel opening and handling works and they will adapt accordingly.
HRS field control and measurement:
- Request from Marco Buzio TE/MSC to house a full 19" rack. Keep proposed position in 170 R-020 with cables through existing passage (if fits with Ar/N2 and AC tubes). Discuss and validate at the ICL meeting (16/04).

Experiments related activities in the experimental hall 5mSpeakers: Hanne Heylen (CERN), Oscar Fjeld (CERN)
Upcoming experimental activities
-
VITO LN2 and LHe2 -> possible to move the nacelle today or tomorrow to allow this or too complicated?
- Plan B is to do it on Monday
- Measurements with samples at IDS now until end of April --> What about EN/EL in RC6?
- Wisard campaign in June - July
- Craning requirements have been collected, information about noise/disruptions transmitted. --> Craning request will need to be taken into account for planning (TBC with Sevrin)
- CRIS measurements 27/4-8/5
- IDS transport the IDS germanium detectors and frame request: 10-14 August
- Availability of sufficient space in front of IDS/RC6 for safe dismantling and handling operations.
- Availability of some space is HIE-ISOLDE where the crane can reach.
- Confirmation that crane operations are possible that week.
- Possibility to use space in the SAS area for transportation of the detector boxes and frame pieces to the parking lot, and possibly short-term storage of components for ~0.5 to 1 day
Coactivity management
Weekly schedule
https://cernbox.cern.ch/s/WPuwNnMp3GkhtvX
Potential issues:
- Friday 24/4: ISOLTRAP craning and PUMA crane removal
- IDS measurements >< RC6 EN/EL
- Monday 20/4 - Friday 24/4 Parking 170 blocked
- LHe2 delivery for ISOLTRAP 22/4
To note
- Thursday 23/4 or Friday 24/4: Transport CM1 from ISOLDE to SM18
- Wed 15th of April until 14th of May: 1 month road closure Democrite
Summary from meeting 1st of April
Week 17 - Monday 20/4-
23/4 CM1 transport
-
24/4 Removal of PUMA adaptation from crane
-
Nacelle to do works, crane is not available
-
Didn't think about this earlier but ISOLTRAP needs to move the usual LN2 craning on Friday -> by that time, the new vacuum-insulated tube for LN2 filling might be available already
-
Installation of scaffolding the suspend last remaining cables on RILIS cabin
-
Check is crane needs to be locked-out or ok if crane remains in HIE-ISOLDE region
Week 18 - Monday 27/4 (4 days only)-
Entire week: drilling of emergency exit of ISOLTRAP platform (noise to be expected)
-
Scaffolding in place (where?)
-
Crane does not need to be locked out but crane is needed to support drilled concrete near the end of the works
-
28/4: VITO magnet transport with crane (1h)
-
Exact timing to be coordinated: RILIS cabin roof hatch opening/laser tables (if they physically fit) and lead handling -> crane needed frequently (1-2 days in total?)
-
Start CRIS measurement campaign
Week 19 - Monday 4/5-
Start EN-ACE works to dismantle RILIS light structure (crane needed occasionally, certain amount of noise to be expected)
-
Continue CRIS measurement campaign
508
- Water leak next to transformers (?) 508
- Long pipes next to 508 - EN/CV
- Technical galleries works - status relaunched

Experiments related activities in the experimental hall 5mSpeaker: Erwin Siesling (CERN)
ISOLTRAP:
- Emergency wall cutting/carrotage: VIC scheduled for 15/04. Wall cutting/core drilling scheduled for week 18 (27-30 April) (Severin/contractor). Crane needs a lock-out during 3-4 days (after CM1 handling and in line with ISOLTRAP activities but RILIS activities to be checked)
- Attention: This is now clashing with the foreseen crane modification / RILIS laser tables removal: Suggestion - Dismount the PUMA equipment Friday 24th April and re-mount them in week 19 (4-8 May). The modification of the drum and electrical box and brackets will need time during which the laser tables and ISOLTRAP wall cutting can take place in week 18 (27 - 30 April). - planning to agree on and to validate. - Preparations mezzanine side done. ISOLTRAP side cable tray bracket and pipe holders to be removed (Oscar/Erwin).
- ISOLTRAP platform replacement work: 18th June scaffolding - first platform part to finish ~22 July.
- Platform replacement preparations: VITO laser tube (high section) and tall pillar removal to be organised. VITO has been informed (Mark, Magda, Nikolay) -> to be done. Request to have the tube back in place as soon as the scaffolding is in place / fixed to the scaffolding to facilitate VITO to run their laser - to discuss with contractor.
- ISOLTRAP filling / dewar craning in line with the CM1 handling activities in wk 16 / 17 (see CM1 activities).
WISARD:
- Has the following request by WISARD been validated? :
- planning to come 15 - 19 June to mount the setup for off line data taking
- week 27 (29 June) to cooldown the magnet
- taking data wk27-29 until July 19
- Verification: clash with ISOLTRAP work? Crane needed for dewar craning WISARD
Beamlines:- Escape routes under the beamlines been clarified? (in the frame of the new pillars for the new RILIS barrack). (Kati, Andreas Herty DSO/BE, Letizia Di Giulio DSO/EP, et all.)
- Compressed air was stoped 1/2 day on Thursday 9 April - had no impact?
- Reminder of compressed air issue at GHM (hissing sound - mail Laura 20/3)
- Guillermo will replace the valve at a convenient moment (after ventilation is back (27 April) / pumping can be started)
- VITO is preparing move of magnet to 275, timing will be adapted taking into account other hall activities - as of week 19?
- VITO move of equipment
- Jura side HIE tunnel has been cleared - many thanks! Tunnel roof and CM1 andling activities 13 - 17 April.
- ISOLTRAP platform
- Wall cutting emergency exit - wk 18
- Check general status of the hall done in preparation of the CM1 handling and transport - 1 April. SAS and handling zone now practically empty: Please maintain this situation until after 23rd April (CM1 transport to SM18).
- PUMA - drilling of holes in the floor ongoind for mounting the RC7 supports and equipment
- Emergency wall cutting/carrotage: VIC scheduled for 15/04. Wall cutting/core drilling scheduled for week 18 (27-30 April) (Severin/contractor). Crane needs a lock-out during 3-4 days (after CM1 handling and in line with ISOLTRAP activities but RILIS activities to be checked)
