[Dsg-rich] Inventory of RICH aerogel at JLab

[Tyler Lemon]

Hello, 

Attached are diagrams showing the aerogel we have on hand at JLab. Tiles we have are colored in green. 

The table below details the quantities of aerogel tiles that are required for RICH, how many are on hand at JLab, and how many are still needed. 

Aerogel Thickness [cm] 
	Tile Geometry 
	Number Required 
	Number at JLab 
	Number of Tiles Still Needed 

2-cm thick 
	Whole 
	24 
	25 
	0 

Partial 
	14 
	0 
	14 


3-cm thick 

	Whole 
	72 
	50 
	22 

Large Partial 
	8 
	3 
	5 

Small Partial 
	8 
	5 
	3 


Considering that we do not have enough partial 2-cm tiles or any 3-cm tiles on hand at JLab for RICH, should we expect more aerogel to be delivered to JLab? 

Please let us know. 

Best regards, 
Tyler
