== Agenda ==

1. Hardware discussion:\\

Quad stages:
Supplier has been reached out to for a quote for 2 xyz motorised stages for the quadrupoles.

Design (R.G):
Demonstrates viewing window, manual insertion state for scintillator to monitor beam profile close to focus. 
Discussion of RCF- to use instead of Thompson parabola at plane of cells, Thompson used to set up beam.
Kapton window before cells.

2. Bio updates:\\

Carousel design finished. Conveyer belt like system, 10 cell plates at a time maximum as vertical suspension with little media results in cells drying. Suggestion to add RCF as one of samples- discussion of scintillator being used, both unlikely to be needed.

Discussion of copper activation for instrumentation- activate stack of copper in proton beam where cells would be, count gamma & measure half life.

3. Beam simulations:\\

Decision was made to search for alternative quad positioning within 1.3m as to not interfere with Thompsons parabola positioning- good signal at current position. Decision was also made to look for a 2 quadrupole set up rather than 4 to save time/ money on initial experiments. 

4. AOB:\\

Discussion of meeting/half day for updates on all sides of PoPLaR. Poll sent out.
