From Chief Technology Officer Sergey Belomestnykh: OCTO’s top five

Sergey Belomestnykh

The CTO group held an all-hands meeting on Monday, May 6. Here is the top five from that meeting.

  1. Safety first. Remember to be safe at all times, at the lab and at home. Human Performance Improvement offers tools to avoid unwanted outcomes triggered by human error. Please complete your ITNA trainings. Pine Street pedestrian crossings between Technology Campus and IARC/HAB will be upgraded with pedestrian-activated flashing LED signs this summer.
  2. PIP-II. The PIP-II project must receive CD-2 (meaning it must be baselined) by the end of 2019. APS-TD plays a key role in designing and building a modern SRF linac and cryogenic system to provide powerful beams of neutrinos for LBNF/DUNE.
  3. All project must succeed. APS-TD plays a key role in several major projects, and while PIP-II is a priority we must succeed in all of them. LCLS-II: Sixteen cryomodules have been assembled and tested with world record performance, and seven have been delivered to SLAC. New cryomodules are sent every two weeks. All of the cryogenic distribution system components have been delivered to SLAC. While the project is going full speed toward being completed in FY20, the new LCLS-II HE project has been launched with a new team led by Anna Grassellino. LCLS-II HE will require even higher level of cavity performance, and the team is already working full speed on that. HL-LHC AUP: The Accelerator Upgrade Project has received the CD-2/3b approval in February, a very important milestone for the Lab and for APS-TD. The coil fabrication is ramping up in IB3: nine of the 49 coils for the upgrade have been completed. Mu2e: Work on the transport solenoid modules for Mu2e is well underway. The inner warm bore and thermal shield assembly have been completed, and support frames have been completed for all solenoids.
  4. Research Highlights. Research plays crucial role as pushing the performance envelopes of SRF cavities and SC magnets can enable future projects at the Lab and around the world. Our research continues to push the boundaries of these technologies. SRF: Several new results on high Q/high gradient demonstrate that niobium continues to show new world records for both Q and accelerating gradients, providing the foundation for new exciting projects, e.g. LCLS-II HE or ILC upgrade to higher luminosity and/or energy. A 1.3 GHz Nb3Sn cavity has recently demonstrated a world record accelerating field for this material, with a 25% improvement over the state of the art. SC magnets and materials: The 15 T dipole demonstrator magnet is getting ready to be tested in May. New Nb3Sn conductors are under development. One of them, employing artificial pinning centers, reached record current density, exceeding FCC specifications.
  5. Construction and renovation around APS-TD. ICB-A construction is progressing well. The high bay area will host the production floor for HL-LHC AUP cryomodules, while new quantum labs and modern and open collaborative spaces are planned for other areas of the building. In addition, we continue modernizing the look of our Division, renovating working and lab spaces for the Division employees.
