- flash = high dose rights per pusle (and short bursts) -> similar to high single bunch currents (special dynamcis which I studied)
-> metrological challenges -> I know.
coming from beam diagnostics?
- precise current measurement with BCTs /ICT/ACCT.
(weird question can we use synchrotron light? from a bend of the electron transfer line, at least relative calibration? fast optical diode?)

KIT advantages
laser based sources -> one is coming.
- could we couple out electron bunches at c-start? at different times after injection -> different bunch length, so could do can of effect of bunch length?
- the virtual diagnostic for flute (indicates that good knowledge of accelerator) could be helpful to adjust machine settings according to measured radiation doses or similar?
- flute not high charge but kurze pulse! grenze für kurze pulse in dosimetry pushen?
- ATP
- HEIKA?
- neugebackenes Zentrum HealthTechnologies

Questions.
- flash is all about particle beams right?, so low alpha at 2.5GeV does not help even so it might provide short x ray pulses? -> also x-ray flash (x-ray energy conventional therapy >=6MeV, but only 100keV at ESRF s41571-022-00697-z-1_overview_FLASH_therapy.pdf, KARA kritische Energy bei 2.5GeV nur 6.2keV, vlt bis 50keV etwas fluss?)
TODO: microbeams only x-ray? only at 3rd generation lightsources as parallel beam with low emittance necessary??? (see ESRF https://www.esrf.fr/home/UsersAndScience/Experiments/CBS/ID17/mrt-1.html) -> KARA???
What about not generating with mask but with structured electron beam
can electrons be used in MRT (microbeam radiotherapy)?
pulse charakteristik bunch strukture, mikro beams
probleme auch pulse längen messung nicht nur charge
räumliches pattern wichtig (mikrobeams) als weiterer schwerpunkt zu flash (was nur kurz sagt)
aber spatial light modulator kann auch die unebenheit der kathode compensieren oder für bessere (transveres) flat top pulse sorgen die hilfreich für berechnung von spacecharge zeug sein kann.
