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 Tuesday 6/29/21
  • Created github repository to advertise my poor coding practices
  • Began mapping shielding measurements for Lead, BorAl, and various Poly

6/28/21

  • Continued BorAl/Borated Poly attenuation measurements with He3 tube
  • Began working with MCNP
  • Continued to map out BorAl placement and shielding design for feasibility study
    • We need more BorAl

6/29/21

  • Finished BorAl/Borated Poly attenuation measurements
  • Got signal from HPGe detector
  • Discussed various poly box and shielding arrangements for feasibility study
    • Designs need to be drawn up
    • Lead tunnel needs to be made bigger to accommodate HPGe detector
      • Will probably need to model another cradle for HPGe
    • Need to source more regular poly and cut it to appropriate length and widths

6/30/21

  • Sourced regular poly and lead sheets, will be washed and brought to clean room today
  • Finalized design of poly box for feasibility study
    • Will have to cut some poly blocks to fit the needed dimensions
  • Finished designing poly brick thermalizing box and lead shielding
  • Brought poly down to LDS in dark room to be washed
  • Tony and Paul were able to get a good signal out of HPGe detector

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
