Hi Fernando,

We would like to keep the cosmic-ray trigger setup for some time, and 
this includes the NIM electronic racks. If necessary we could order 
cables to meet the safety requirements to replace the ones that are in 
place and I can work with you to come up with a plan to do this. We will 
need to get a cost estimate and order them before the end of the fiscal 
year.

Thanks, Elton.
