= LhARA Weekly Meeting 21^st^ July 2020; 14:00 BST = == Summary of actions == * **KL**: Create draft response to referees. * **KL**: Create ICHEP talk rehearsal slot for week of 27Jul20 **Present:** JPar, KL, AK, TSD, AP, AG, HTL, TG, WS, PA, CW, OE, JPa, RB, JM == Notes == 1. [wiki:Research/DesignStudy/Meetings/2020/2020-07-14 Notes of previous meetings] and actions: * **KL**: Create draft response to referees. * **Stands.** * **KL/WS**: to exchange emails with AK re "restart" of experiment and simulation meetings. * **Done.** Will do same as before, ~30 mins, will do it on Tuesday PM. Do it just before LhARA meeting. Use same ZOOM booking. * **KL**: Organise LhARA logo competition. * **Done.** 2. Status of pre-CDR publication: **KL/All** \\ Referees' comments have been received: see the top of the [wiki:Research/DesignStudy/PreCDR/Publication pre-CDR publication wiki page]. \\ [raw-attachment:2020-07-21-Response.pdf​ Skeleton of response document]. \\ We reviewed the referees comments and discussed our responses. We agreed that a draft response and revised paper would be circulated this Friday. 3. Preparation of response to referees: **KL, ALL** * Next week. 4. Updates: - Capture section: **CW** - Working towards ERC proposal. In particular, trying to get a consistent project plan. TSD and HTL continue to make good progress and will provide updates below. - Simulation: - Particle production at laser target: **HTL** - HTL is checking the convergence, now focusing on the dependence of the spectrum on the cell size. He has initial particle distributions which he is now starting to analyse. A long, high-resolution run is "in the computer" and will be analysed when it is complete (Thursday). - TG: notes that he has seen a [https://doi.org/10.1038/s42005-019-0140-x paper] in which two beams at 90^o^ to each other, each at 45^o^ to the foil are used to increase particle production. RB commented that there are studies TNSA can be enhanced by sending a second pulse and exploiting its ponderomotive force to enhance production. OE notes that such schemes could be used for LhARA, but had specified simplest. - Gabor lens simulation: **TSD** - TSD has looked into simulation for first simulation of the lens. Dynamics of electrons in lens is being considered. At the present he has not been able to create a discharge and is investigating why a discharge is not initiated. The execution speed is also being investigated. Also worrying about speed. At the last meeting a discussion was initiated about the relative priorities of the various simulations in the light of the ERC proposal deadline. - Any other simulation - No further update. OPAL installation underway on IC cluster underway. Some issues being addressed with S.Fayer. 5. Status of preparation of Expression of Interest for the [https://epsrc.ukri.org/funding/calls/second-call-for-transformative-healthcare-technologies-pre-announcement-and-engagement-event/ EPSRC Transformative Healthcare Technologies call]: **KL, ALL** \\ We discussed the possible scope of the proposal. We identified the need to address the principle risks in the initial R&D programme. Therefore the following threads needed to be included in the proposal: * Laser-driven source, Gabor lens, and their integration; * Instrumentation, diagnostics, and dosimetry; - We identified three sub-themes: - Beam: distructive and non-distructive; - Biological end-station: e.g. "proto"-acoustic imaging, ... - Near clinical: dosimetry, position-dependent dosimetry, micro-dosimetry ... * Conceptual/technical design of stage 1 and stage 2 * Active participation in radiobiological investigation //Need for: // * [raw-attachment:Slide_v3.pdf​ New "institute collage" for talks and publicity]: **TSD** \\ [raw-attachment:Slide_v3.pdf Updated institute slide released after the meeting.] All are asked to comment. * LhARA logo competition: \\ Temporary [wiki:Research/DesignStudy/LhARA-logo-competition page on wiki] to collate entries has been made. KL is keeping the mapping of "entry Id" to designer. 6. Conference contributions: **All** * ICHEP -- Parallel session contributing; see http://ichep2020.org - [raw-attachment:2020-07-29-LONG-ICHEP-LhARA-d1.pptx Draft slides] \\ We agreed that **all** would send comments on the slides and that **KL** would book a rehearsal slot for next week. 7.
