[Clas12_rich] RICH electronics- summary of space needed

[Tyler Lemon]

Hello, 

>From my understanding, the following is all of the electronics components in rack C3-5 for the first RICH sector and their dimension: 

RICH 1 Components in Rack C3-5: 

	Component 
	Height [U] 

	VXS crate 
	11 

	CAEN power supply 
	8 

	HV distribution 
	5 

	Fiber Distribution 
	4 

	Empty space for ventilation 
	4 

	TOTAL 
	32 





RICH 2 Components in Rack C3-7: 
	Component 
	Height [U] 

	CAEN power supply 
	8 

	HV distribution 
	5 

	Fiber Distribution 
	4 

	Empty space for ventilation 
	4 

	TOTAL 
	21 





It looks like in rack C3-7, there will be the 21U for RICH 2's components. 


However, it looks like it will be a lot tighter fit for the first RICH sector's electronics in rack C3-5 since there is only 23U available. Regarding this: 

    1. Would it be possible to drop the existing HV supply in C3-5 down a few U to make space? 
    2. Matteo had mentioned that the Fiber distribution might be able go behind the VXS crate. Is this still a possibility? 
    3. Would the CAEN HV mainframe be able to go on top in the rack so there is nothing on top of it and open to the air? 


Considering these questions, it might still be possible to fit the components for RICH 1 in rack C3-5 with a little bit of rearranging of what is already there. 

Best regards, 

Tyler
