◦ Need to get Experimental Control Procedures (ECP) documents done

Cross training with other staff member

◦ Cross training 9T with Cedric and Donna from 7/5-7/15. – finished!

Procurements

◦ New compressors for HFBS and NSE TLCCR

◦ 9T repair and 15T maintenance

Maintenance of equipments

◦ 9T: 4G-150 power supply fixed. Found short between the terminals and ground ~300 Ohm at room T. Now getting quotes from Cryogenic Limited. ◦ 10T: New lakeshore 336 installed. Installing a smaller LN2 trap in the helium circulation loop for future automatic liquid nitrogen refill, will assemble everything and start a 

new test. Getting quote of a new TLCCR inside 10T. ◦ 15T: Working fine during last test. Oxford will fix the lambda fridge pumping line, repair the loose current leads, leak test everything and replace the old magnet power 

supply with newer mercury version. AMD processing. ◦ SANS orange cryostat indium seals replacement ◦ Test automatic gas loading cart with Juscelino on different beamlines, BT1, HFBS, SANS...

◦ New LIPPS Labview program after a new control box made by Juscelino – finished!
Specialty projects

◦ Labview automatic NV control with Yegor – finished! ◦ A setup to combine Orange cryostat with Titan magnet so users are able to reach below 2K in Titan magnet – finished! ◦ Design and make new silicon tail for Candor CCR – finished! ◦ Get labview to work under Linux system so that it can be used like a compactRIO

◦ Sergiy’s low T goniometer communication with NICE

◦ 3-syringe-pump system programming ◦ Time stamping of the SE equipments using compactRIO, everything working, server/client, automatically detect COM ports

Misc. ◦ plug-and- play SE with Krzywon, Maliszewskyj and Peter Beaucage. ◦ Keep reviewing new 7T/12T drawings

◦ Help Mads to get the potentiostat working on the CCR and programming – finished! ◦ Work with Rebecca Dally to design sample holders – finished! ◦ Successfully established communication between Eurotherm 2404 temperature controllers and PC using modbus – finished! ◦ Keep updating all sample environment webpages including all equipments in all the labs

◦ New compressors for HFBS and NSE TLCCR waiting to be installed and tested

◦ Remote control of compressors at PBR

◦ Labview version controls and documentations.

circulation loop for future automatic liquid nitrogen refill ◦ Will assemble everything and start a new test ◦ Getting quote of a new TLCCR inside 10T.
Maintenance of equipments – 15T

◦ Working fine during last test in February, 2022

Tvti=1.50K, Tsample=1.51K

B field ramp up to 14T and back to zero. ◦ Oxford will fix the lambda fridge pumping line

◦ Repair the loose current leads

◦ Leak test everything

Old vesion New vesion
Specialty projects

◦ A setup to combine Orange cryostat with Titan magnet so users 

are able to reach below 2K in Titan magnet – finished!

Base T1kpot=1.535K, Tsample=1.95K

Can hold at base T for 46 hours with one helium refill

Temperature change without any problems

Base T1kpot=1.515K, Tsample=2.03K

Temperature change without any problems
Results

3-sample holder base T (2.03K) is 0.08K higher than the 2-sample holder base T(1.95K)

Pros: ◦ Can reach lower T (~2K) than CCRs (~5k) ◦ Other SANS tails can also fit on this OC.

Cons: ◦ You have to warm up the entire OC for a sample change, turn around time is around 12 hours min. ◦ Need the vacuum chamber pumped by turbo at all times. ◦ More support structure on top of Titan
Specialty projects

◦ Design and make new silicon tail for Candor CCR – finished!
