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
July
7/1/21
- Need to talk to CoSE IT to get new DAQ computer and find out how to link into HPGe detector through switch in clean room
Future tasks not on meeting task list
- Create attenuation plot for He3 with BorAl
- Model thermalizing box and make sure design will fit within wanted parameters
- Draw cuts on BorAl pieces and find out how much more will be needed
