== Minutes for UCL Proton Beam Therapy Group Meetings, 18th September ==

=== Present ===

'''Joe Bateman''', '''Sonia Escribano''', '''Febian''', '''Simon Jolly''', '''Raffaella Radogna (via zoom) '''

* Pushing for masters student to complete analysis of SciFi monitor (but not with protons from Linear Beam)
* It is okay for measurement of the beam spot position through the centroid of the cluster
* Beam size measurements very sensitive to geometric variation between coupling between pixels and fibres - need to find a way to calibrate fibre response
** Pixel sharing between fibres due to pixel pitch
* Potential calibration method through shining collimated light onto each of the fibres 
* Noticing reduced intensity on the central pixels
* Has travel money to use up before end of 2024 - plans to come to UCL.
** w/b of 28th October to look at SciFi tracker and discuss integrated design
** Possible second trip in December for beam test if new electronics and scintillator sheets are ready 

=== [[ELogs/Febian|Febian]] === 

* Upcoming CDT event on 24/10 to present a 2 minute presentation and poster 


=== [[ELogs/JosephBateman|Joseph Bateman]] === 

* Working on scripting for sourcing the relevant environments to run Geant4 via CVMFS on the cluster.
* Joe and Simon had meeting w/ Ilaria and Giorgio from Maastro to discuss more about FRED-MC for dose reconstruction from QuADProBe measurements and the hardware requirements etc.

=== [[ELogs/SoniaEscribano|Sonia Escribano]] === 

* Preparing a talk for the Science Slam session at the DKFZ Medical Physics Summer School
* Suggestions for QuARC Calibration Issues:
** Compare the method Saad was using and the new method with the old shoot through files 
** Check with the Manchester and PARTREC data 
* To check up on status of scintillators and follow up with Harry & Martin

=== [[ELogs/SimonJolly|Simon Jolly]] === 

* Harry has been in charge of dealing with scintillator sheets but has been occupied by SuperNEMO
* Have rough cuts from nuvia - either go to Daytron high precision machinery or to someone who has one of these machines. Daytron can do better 10 um flatness
* Need Martin to machine the flatness 

* Things needed to sort before next beam test:
** Oxford to do small changes to zmod board
** Pete Hastings have new ddc boards
** New scintillators for a full stack - 
** If doing full QuADProBe test only need two stacks 

* Plan for PTCOG Argentina Talk:
** Full 3D treatment plan MC reconstruction with log file data and QuADProBe measurements at Maastro and at PSI 
** Unsure whether SciFi tracker will be available so will likely have to use Tony's CMOS sensor again if available.

* Aim for QuARC beam test before end of 2024 - at UCLH
