 **ZOOM:** https://imperial-ac-uk.zoom.us/j/98220889714?pwd=SM90vOF7BKSXoU3mD9q7OwBQo4IVB3.1 
 
-== Meeting Agenda == 
+Attended: PH, JMcG, AFr, MH, JPi, CD
+
+== Meeting Notes == 
 
 1. Overview of desired paper and required aims for next SCAPA beamtime
  - Dates: July/August
 
-Mark timepix to do some alpha work and could test LET at SCAPA
-OSLs 
-
 2. Steps before next beamtime and discussion 
+ - Document: https://docs.google.com/document/d/1OTARVtxhLRu02S6CLdRDB2QlGvCqDfZ3aWBifjIFs_Q/edit?usp=sharing
+ - Do we have a set beamtime?
+ - Cell control tests should be done with irradiated cells as well
+  - Can use Marie's lab
+ - Mark has a Timepix detector to use as an alpha-particle detector and OSL he will test.
+  - If successful, can bring to SCAPA as LET detectors
 
 3. Discussion of aims post-October
- - Anything we can do in the next beamtime to build towards these
 
 4. Aims for ELI
  - Thanks to Emma for coordinating the bid
- - Rough dates?
+ - Josie requires more details on the low energy beams at ELI. Currently, can only find information on the 68MeV beams.
+  - Calvin to ask Robbie tomorrow.
 
 5. Quick updates
  - In-beam diagnostic
-  - PH: Presentation on hollow fibre readout plan
-Plastic silicone fibre with a hollow (vacuum/air) core and Peter has ordered some. 1m away gets 0.08% but any bending will decrease that substantially
-Ordered 1.6mm. Get 0.14% at ~1m of hollow fibre. Pass through a 10mm chunk of glass. Got a black box lens from manufacturer for correct simulation. Start with this for experiment and then decide on which size we actually need for optimised travelling
-Beinding does need to be fixed!
-Losses can be bent to the pwoer
+  - PH: Presentation on hollow fibre readout plan [raw-attachment:something.pdf Slides]
+   - Peter has ordered some plastic silicone fibre with hollow core.
+   - Zemax simulations show a fibre with a 1.6mm core has 0.14% to ~1m away.
+   - Bending must be constant so require tubing and stands to hold the fibres in place 
+   - Must consider the 10mm thick glass porthole
+   - Need the dimensions of the vacuum chamber to be able to recreate and test at Imperial
  - Bioprep
+  - None
  - SCAPA
+  - None
