37. Looking back at the Hardware commissioning & Magnet training (20' + 10')

Andrea Apollonio (CERN)

11/23/21, 10:30 AM

This presentation summarises the experience with the LHC powering tests following the Long Shudown 2, also in the context of previous hardware commissioning campaigns. The talk will focus on the successful execution of the various commissioning steps, highlighting the encountered problems, the identified solutions and key decisions taken, with particular emphasis on the training phase of the...

7. Results and lessons learned from the 2021 beam test (20' + 10')

Michi Hostettler (CERN)

11/23/21, 11:00 AM

The two weeks of beam test in October 2021 marked an important milestone in the re-commissioning of the LHC after the Long Shutdown 2 (LS2). After almost 3 years of shutdown, first beams were back circulating in the LHC as of October 19, 2021. After one week of setup with pilot bunches, collisions were re-established with nominal bunches at 450 GeV.
This contribution summarises the main...

6. Status of the Maintenance Period and Plans for the YETS (20' + 10')

Marzia Bernardini (CERN)

11/23/21, 11:30 AM

The talk will give an overview of the Year End technical Stop 2021-22, including the activities related to the RF finger repair in S23, maintenances, consolidation and HL-LHC. The methodology of the handover between EN-ACE and BE-OP will be also described identifying major milestones.
The frame of programmed stops during run 3 will be commented, explaining the methodology which will be in...

8. The Injectors: What to expect when (20' + 10'')

Alexander Huschauer (CERN)

11/23/21, 12:00 PM

In the framework of the LIU project, the whole injector chain has undergone substantial modifications during LS2. While 2021 operations in the injectors has mostly focused on the the re-establishment of pre-LS2 beam performance of the non-LHC-type fixed target beams, a large effort has been invested to commission the LHC proton and lead ion beams during machine development and special...
