+== Meeting Notes == 
 
 1. Alternate Beamlines
  - ELIMED part of the next ELI submission
   - There appear to be calls for ELIMED every year
+ - 20th October 12:00 (noon)
+  - Unlikely to make this deadline
+  - Cannot make a submission repeating the same missing details 
+ - BUT:
+  - **Calvin to share the document**
+  - **Ken and Josie to nudge the bioplan into action**
 
 2. BioPrep
- - Check where the transwells are being delivered to
- - Alex seen SCAPA?
- - General Updates
+ - Alex seen SCAPA
+  - Yes and transwells have been agreed to be the best way forward
+ - Transwells
+  - Cost ~£1000
+ - February puts the bio team on a timetable
+ - Need a stronger bio/SCAPA presence at these meetings
+  - **Colin to reach out to Marie**
+  - **Colin to reach out to the SCAPA team to confirm February is our goal**
 
 3. Instrumentation
  - RCF
-  - Updates on delaminated EBT4 (Got some from Ben Phoenix?)
+  - Updates on delaminated EBT4
+   - No longer sold unless for 100 boxes or more
+   - Need 35 more boxes to get an order
+  - Mark found a different type of film
+   - Tony has requested a free sample to check it out
+   - Tony has two master's students on cmos and can compare to the new film
  - SciFi
   - Construction pad is built
- - Fast electrons
-  - Need a better understanding of the electron-to-proton distribution
+  - Appears to be no sensitivity to rotation of the array (as expected)
+ - Thin wall ion chamber
+  - On-line detector uses protons
+  - Thin window (10s of um of Mylar)
+  - Concern is mainly recombination at the time of ionisation because of the intense pulse
+   - Will still see a residual ionisation
+ - Diamond detector
+  - Off-line using the electrons
+  - Need a better understanding of the electrons to understand its feasibility
+ - **Richard to discuss thin wall detectors and diamond detectors at a Tuesday meeting**
+ - Calorimeter
+  - Measure the energy by measuring the temperature change in graphite
+  - Most stable and understood measure of dose
+  - If we had £10K can ask the same company NPL asked to make a transcal detector thin enough for our energies
+  - Sam Flynn's detector that has been discussed before
+  - Longer term benefit is thatthey're known compared with something like air fluoresence which is not as well known
+ - Further discussion:
+  - Need to group these diagnostics into:
+   - In-beam beamline diagnostics
+   - Dosimetry run at the same time as cells. Measuring the dose in the cells. eg ion-acoustic
+   - Measuring the dose of the low-energy beams to establish stability
+  - As always, beamtime available in Birmingham
+   - **Ken, Simon, Calvin and Josie to discuss next week**
 
 4. SCAPA
  - Updates
+  - No update
