CH PAS Master Timeline

Timeline

This page will be used to document when each task is started/completed as a master reference for all work accomplished. The plan is to make my life easier when I have to look through months of work.

May

5/10/21

• Attended intern orientation for first day at INL

• Completed training this week as well as began NaI plateau setup

5/11/21

• Put first coat of paint onto lead bricks to be used as shielding in PAS experiment

5/12/21

• Moved steel table from LDS to clean room and began set up

5/17/21

• Sheared a lead sheet into 6 rough 3"x3" squares to be used for attenuation measurements with NaI detectors

• Lead sheet pieces were wiped down with a wet wipe, duct taped, rewiped, and hammered flat.

5/18/21

• Began data collection for NaI plateau and operating point measurements

• Began writing analysis code for NaI plateau measurements

5/27/21

• Finished painting lead bricks and left to cure

Unknown time when tasks were completed

• Gathered borated poly with Paul

• Tested NaI detectors and found one working base

June

6/1/21

• Moved dried/cured painted lead bricks from painting area to clean room

• Cleaned each brick with a wet wipe before transition into clean room, will be allowed to air dry on steel table

• • 50 bricks total: 49 half bricks and 1 full brick

• Steel table set up finished

6/4/21

• Created initial lead brick tunnel

6/8/21

• Finished collection and analysis of NaI detector plateau measurements, voltages ranging from 700V to 1400V

• • Analysis included Souce in & Source out plots, Signal:Noise, and background subtracted plots

6/9/21

• Began data colleciton for He3 Borated Poly attenuation study

6/11/21

• Finished data collection for He3 Borated Poly attenuation study

• Began writing analysis code for Borated Poly attenuation study

6/21/21

• Spent the day at INL with Chuting and Paul

6/22/21

• Finished writing analysis code for He3 Borated Poly attenuation measurements and submitted plot to Paul

• Began designing cradle for NaI detector using fusion360

6/24/21

• Finished modeling cradle and sent designs to Jeff Burggraf who offered to print it for me

6/25/21

• Began BorAl attenuation measurements including overnight background runs

6/26/21

• First BorAl background run lasted 60000 seconds and ended at approximately 11:45am 6/26/21

• Continuing to run Borated Poly attenuation measurements with BorAl surrounding He3 tube

• Cradle for NaI detector has been printed and should be in lab Monday 6/28/21

• Created github repository to advertise my poor coding practices

• Began mapping shielding measurements for Lead, BorAl, and Poly

Unknown time when tasks were completed

• Found a fifth NaI detector (no base) with smaller crystal diameter (5.5cm)

• Helped Tony and Joe moved DD generator from nuke eng department and subsequently lift into clean room

• Moved HPGe detector into clean room and unpacked it, Paul has begun preliminary functionality testing
