hi Zhenyu,
	I think it is not a good idea to write "ES&H: TBC" anywehere in this 
presentation. If it is TBC, and you are quite confident it won't be a problem, 
then better just drop the text "ES&H: TBC". It adds no value to the presentation 
and just begs questions. If you're not confident, well...
	The safety committee probably likes to see datasheets on all referenced special 
materials. I guess the plan is that comes separately from the presetation? That 
makes sense, how it was done in the past as I recall.
	Do you have any reference on the safety acceptability of cadmium plating on the 
cooling tube? You may be asked about this, I guess. It would be best if you can 
quickly knock down any objection to it by reference to some industry 
specification or to prior use at RHIC or something.
        My opinions anyway...

                Gerard
