Top five from the chief technology officer and Applied Physics and Superconducting Technology Division

Sergey Belomestnykh

On Jan. 13, the Applied Physics and Superconducting Technology Division held an all-hands meeting. Here are the top five takeaways from the meeting:

  1. Safety comes first. A new FESHM chapter helps define clear roles and responsibilities and clarify the expectations of when a formal work plan is required. Workshops will be organized for groups involved in work planning. In addition, the current HA system will be upgraded to centralize permits, hazard analyses, and approvals through IMPACT. Remember to pay attention to your bodies to avoid industrial ergonomic related injuries. Keep your ITNAs current, your workplace clean, and be safe out there.
  2. We’ve made strong progress on a key lab project: PIP-II. APS-TD provides most of the resources for the PIP-II SRF linac, cryoplant, and cryogenic distribution system. The half-wave resonator cryomodule from Argonne has been transported to PIP2IT, and the system setup is in progress in the test cave. The SSR1 prototype cryomodule assembly is completed and headed to CMTF as well. Both cryomodules will be tested at PIP2IT with and without beam in the coming months. Other cavities, like HB650, have exceeded their specifications. PP2IT cryogenic system is commissioned for 2 K operation. The cryoplant building layout is completed, and an award in progress. Thanks to everyone for your hard work on this effort, which is essential to make LBNF and DUNE a success.
  3. LCLS-II had a great year in 2019. We’ve finished seven cryomodules, tested nine, and shipped 15. We’ve also completed the delivery for all components of the cryogenic distribution system. A great job by the team means that we met or beat our cost and schedule goals, solved problems quickly, and became proficient in building and testing cryomodules. Now we’re moving on to work on 3.9 GHz cryomodules, where we’ll face new challenges. Keep up the great work! We’re expected to wrap things up around July 2020.
  4. Our sector is involved in a variety of high-profile projects. People in our sector are tackling all sorts of technically challenging and important experiments and projects. R&D to develop an improved nitrogen doping for LCLS-II HE was successful, and the team is preparing to start building the pre-production cryomodule. There have been successful tests of the LHC AUP magnets, Test Stand 4 refurbishment and upgrade is underway for spring Zero Magnet Test. There was good progress in other areas as well: dilution refrigerator for SuperCDMS was successfully cooled down, fabrication of feedboxes for Mu2e is nearing completion. Formula for project success: Sound engineering + Detailed design + Rigorous QC of components + Tight control of work processes (including scientific oversight) + Experienced & dedicated team + High priority = Success!
  5. Ongoing and sustained upgrades of facilities are key to future successes. The division continues to upgrade our test and production facilities. In particular, the new IB4 versatile CVD/ALD furnace will be instrumental for innovative engineering of SRF surfaces. Materials Science Lab is getting a dual beam SEM/FIB for ultra-high-resolution material analysis and high-quality 3D characterization. IB1 gaseous helium system is being upgraded with several Tevatron storage tanks.
