We produce a short proton beam from a picosecond CO2 laser ionized H2 plasma.
The protons have a velocity distribution between 0.01-0.2 c (17 MeV) and ideally
time resolution of 250 ps would show me the energy spectrum of protons on each
laser shot. There is a high energy ion peak with a narrow energy spread. In my
opinion the diagnostic will be of interest for the entire laser driven ion
acceleration community, since such a single-shot measurement technique on MeV
level of particles without restricting an aperture of the beam is important for
many different reasons. To summarize I am interested in collaborating with you.
I think a single element MCP with the smallest pores and conical anode with
resistance of 50 Om will be an ideal one. However, we can try first a detector
you have. What in you opinion can be a response of the MCP on an ultrafst
perturbation? How difficult to make a detector with a single element and what
time resolution it can provide?
