Abstract:
This target has seen some irregular beam patterns 
Possibility that the beam hit the walls of the target tube or even the cooling fins
This PIE we want to investigate how the irregular beam physically affected the target

ID: 2698

PIE was performed by Aaron Tam, Directed by Aurelia Laxdal, Observed by Lucas Backes, Special help from Chad Fisher 

External views:

• Windows are clear of any irregularities 
• More pictures of this can be found in RH-ISAC E-log 2728

Internal Views:

• Heatshield internal
  
  • Some discolouration from heat and soot deposits.
  • This seems to be fairly clean to normal amounts - not concerning 
• Target tube
  • tube is bent with the middle higher than the sides
  • Target tube was not removed 9/64ths allen wrench could not be located for this operation 
• Target tube Exit
  • Heatshield windows were punctured to reveal the target tube entraces/exits
  • Entrance is waterline side (ITE)
• Extraction electrode parts were removed from the back off the target
  • These parts look normal
  • some of the extraction electrode would not pull out due to tight fitting parts and the investigation stopped here.

Conclusion: Target physical condition is normal as far as we could investigate

Hot Cell Prep:

• Tools organized, working space cleared, spot for clean tool to sit placed, Air tool is open and spinning clockwise for tightening 

Loading:

• Ta#68 was loaded into pail# 300
• PEEK seal parasitic assemblies loaded (PEEK seals were removed in ID: 2724)
• Farran had some old samples that also went in (More details to come when Farran sends the info)

Lid/latching:

• This went smoothly

Bail attachment:

• Some difficulty in attaching the Lifting Bail, but went on smoothly with the help of Chad
