[EIC-eRD110] [EXTERNAL] Re: [Eic-projdet-pfrich-l] LAPPD magnetic field measurement program, v01

[Kiselev, Alexander]

  Dear Silvia,

  thank you for the feedback. I believe in the present setup it is not possible to measure the spatial resolution precisely, because the fiber has a substantial numerical aperture and there is no focusing optics used. This circumstance is actually mentioned in the text, but I now changed the wording a bit.

  v02 will be distributed (and hopefully becomes final) later today once I collect all other feedback.

  Best regards,
     Alexander.

Dear Alexander,

  thank you for forwarding the document.

Dear All,

the planning looks solid, even if somewhat dense.
In case something should be dropped because of time constrains, I would suggest as
second priority the space resolution. In fact, in my intuitive understanding,
space resolution will not be severely affected by the presence of the B field in
a DC-coupled device. Probably, the space response will be distorted
(= different central value, not so much different resolution),
but the distortion can be measured and then corrected for.

Best greetings, Silvia

  Dear All,

  see v01 attached. Apparently not all of the people involved were on the erd110 mailing list, therefore I'm Cc-ing to other colleagues, just in case. Let's fix the document today and give it over to Mark and Junqi.

  Regards,
    Alexander.
