Jay/Reza, do you have results, or want to say, what the new dipole will look like?

Jay's markup of the original DS fixture media:190815_newDS_markup.pdf

Do we have a coil drawing, Jay says he doesn't believe so?

200KEV coil packages - should they fit, can they fit?

200kV Wien filter - V1 - First iteration to modify CEBAF Wien filter for 200kV operation, fabricated per Jay's proposal, and installed at UITF 2017

Alicia, do you have some feedback on moving the buncher?

Marcy/Phil, can you make a tally/description of all the viewers we have at the injector, e.g. for each one (size, material, wires, holes, good/replace) ?

We have this from a viewer walk in elog https://logbooks.jlab.org/entry/3579289

2I02: chromox, hole

1I02: chromox, hole

1I03: chromox, wires

1I04: chromox, wires

1I07: chromox, wires

0I01: Yag, broken

0I02: chromox, wires

0I04: chopper, larger chromox, wires

0I05: chromox, wires

0I06: chromox, wires

The most recent viewer walk I can find for downstream of this is: https://logbooks.jlab.org/entry/3317347

0I06A: chromox, can't see wires, but probably there

0L01: chromox, wires

0L02: chromox, wires

0L03: chromox, can't see wires, but probably there

Is this the information we need regarding viewers? We can reuse any except the broken YAG, we can reconfigure for 45degree insertion if there is space and hardware, etc.
