Agenda
- Quad positioning & discussion
Simulations presented (2 Quad Combinations.pdf) to show optimal quad positions of the quad combinations using the SCAPA divergence with a pencil beam. 4cm2cm, 6cm4cm and 6cm2cm quads gives best transmission as with previous beam, all above 10% with this beam but while 4cm2cm has lowest transmission of the 3, the position of the first quad is most appropriate and beam shape is more circular at the target- potentially the best option. Sensitivity simulations shifting the quads up to 1mm in the x and y directions show that the quads are very sensitive even at 0.01mm. Quad 1 was much more sensitive than quad 2, automated mounting system should be placed on quad 1. Next step to move the source in the y direction as SCAPA has been having issues with this, see what issues may arise.
- SCAPA Update
Quote for rotation drive- 25k for xyz. Though there are only plans to purchase 1, we should purchase an 8 axis control for future experiments where we plan to add more. Supplier secured for kapton exit window to air for bio samples, awaiting quote. Discussion of having 2 modes of operation, one without quads first (can utilise the december beamline for this) and one with. March beamline available on week of March 10th.
- Bio Update
Carousel design agreed upon, to be implemented into the drawings by Ross to check dimensions are appropriate for beamline.
- AOB
Agenda for half day meeting discussed, roughly 30 mins per presentation. Need for: SCAPA update and state of experiment plans, list of things that are needed for experiment to go ahead with time scales/deadlines (Ross) Bio equipment update and experiment plan, list of things that are needed for experiment to go ahead with time scales/deadlines (Jason/Marie) Hardware discussion, list of things that are needed for experiment to go ahead with time scales/deadlines (Josie, Ken, Hywel) Discussion of all sections Discussion/creation of checklist Timeline plan
