Attended: Justin, Moskov, Hovanes, Jim, Sean, and Igor. Mikhail has a beam in Juelich now.

• On April 8th, we had a Hovanes' CPS meeting for a development of the engineering design of the Tiger hall with CPS [1]. It has Vitaly's slides and was a long discussion with Pavel and radiation situation in the Tiger Hall. Pavel promised to do some estiamtions. Hovanes reported the extended magnetic field using OPERA which Vitaly will use in his CPS calculations.

• On April 14th, we had a Tim's meeting for a development of the engineering design of the collimator alcove with the Be-target assembly and Flux Monitor setting [2]. Tim said that one can accomplish the engineering design this summer of 2022, all looks promising. Hovanes is thinking about a diagnostics.

• On April 22st, we had a Hovanes' meeting for a development of the engineering design of the Tiger hall with CPS [3]. It has Vitaly's slides.

• Pavel provided a radiation condition for CPS following a RadCon regulations as 5 mrem/h on the surface of the CPS assembly in 1 hr after beam is off.

• Miskov said that accelerator folks will buy a new laser to get 128-ns for us.
