Wie  stress the need to finish the Holi lattice as soon as possible.

Blaskiewicz reported that the impedance measurement of the RF cavity is about 1 k-ohm at 7.5 Mhz
Tsoupas reported extraction kicker voltage with increase length  of kicker and kicker voltage for all
four working points are below 35 kV
 Tsoupas also reported progress on the modeling of injection bump magnets 

and measurement of 27CDM30 corrector magnet which were acceptable.


Raparia report on the magnet measurement progress. (A. Jain talk on 0/03/20

 

Raparia also reported that the collimator in the RTBT has moved by 55 cm after Q19.

 

Gerge report that emittance growth due to the sectupoles is about 30% and vertical amplitude about 9% which is closer with UAL.

 

A, Fedotov discussed the emittance growth due to nonlinear setupoles and 

 shown that the with increase in number of particles the asymmetry between straight section almost gone.  fig 1, fig2 fig 3

He also shown the result for numerical saturation 3d space charge modeling.

some of the image charge modeling results fig 2 were shown
