[Grzegorz Kalicy]

Hi Marc, Imani,

I could meet on Friday, or preferably next Monday (10/10/2022).
On Thursday I'm back from DC around 9pm which might be too late for you guys.

Hi Greg,

Thank you for the information. Are you available Monday next week? I would like to walk through this task to get a better understanding of the process.


Thank you,

Imani

Hi Marc,

In principle yes, in HallD we used it to clean mirrors. In our project we will use it to clean bars at the cleaning station before placing them in horseshoes and moving them to darkroom for measurement.

Cheers,

Greg

Hi Greg,

For the Hastilite, will you be using the same manner as in the Hall D projects?

Hi Mark,

I will get the daily operation by the end of next weekend.

The chemicals will be needed for the cleaning station:

- HASTILITE (we can initially use leftover from GLueX DIRC in HallD, I'm waiting on info from Keith on how much is left), Marc Stevens got it approved to be used for HallD

- ultra-pure acetone and ultra-pure isopropanol

- DI water


Just for the records the remaining items for cleaning station outside our dark room:


- Berkshire cloths fro cleaning

- light (a strong halogen light to be able to see pollution and damage, with a fiber optic "goose neck" light guide)

- two regular tables (one for cleaning, one for mounting bars in horseshoes)

- small cart/table for cleaning supplies

- chairs

- HEPA filter for the storage rack and some dust filtration over table

Cheers,

Greg

Hi Greg,

When you have time, can you send over the expected daily operations for the lab.

I'll use this as a template to develop the Task Hazard Analysis.

Also, I need a list of the chemicals needed for cleaning and specific details on the cleaning process you mentioned in the meeting.

We can then plan the space outside the laser controlled area.

Regards,
Marc
