'''AK''':
* Working with pulser and LED.
* Running detector emulator into digitiser produces exact replication of spectra as expected.
* Driving LED with detector emulator more problematic: digitiser won't trigger properly on PMT output.
* Driving LED with regular pulses gives similar response to experimental measurements:
** For Hamamatsu base, mean ADC position (gain) drops with frequency then stabilises around 100kHz;
** For UCL base, ADC mean drops quickly then rises from ~30kHz up to ~450kHz.
* Will try more measurements at lower and higher frequencies.

'''MH''':
* PDFs of layout sent to Clatterbridge and Carsten Welsch: no response as yet...
* Measuring the emittance evolution down the Clatterbridge beamline:
** Original element written by ESA: doesn't work...
** Will write own custom element for specifying input emittance.

'''LK''':
* [http://www.hep.ucl.ac.uk/pbt/wikiData/presentations/2017/LK20170208_ProtonRangeFromPhotons.pdf Looking at getting the proton range (mean proton energy) from a scintillation photon depth distribution].
* Deriving analytic function to describe quenched Bragg Peak very complex...and may not be accurate...
