Items from previous meetings

• Eugene looked into the issue of optimizing the flux of kaon on the hydrogen target by adjusting the angle of the photon beam with respect to the nominal beam direction. His conclusion is that there is no benefit in having a small angle between the photon and the kaon beams. He will show some plots during the next meeting.

• Vitaly compared energy depositions for two different electron beam shapes: FWHM=1.2mm and FWHM=2.5mm. He used the new field map and positioned the radiator at z=-50cm. There was no extra steering magnet. The narrow electron beam also had a narrow beam hole of 3mmx3mm, and the wide beam had a wider beam hole of 6mmx6mm. The wider beam with FWHM=2.5mm resulted in twice smaller energy deposition density at the peak in the copper core.
