SLS parts Our support is in the nose area that the reason we got the deviations in this area. For the next parts we do the re-work at the scan-company.  It makes it easier for us to check the re-work and we can minimize the deviations to 0,2mm or less.

It is the magnetic base material. In future we reduce the quantity of parts and we have a higher allowance. So energy input and consequently the delay should be reduced. The wire of wire EDM should be moves through the allowance without contacting the base plate. For the currently parts IL/ OL we use these changes.  The Laser beam has a focus diameter of ~0,11mm. So it is better to have a radius over 0,5mm.

1. Deviation up to 0.4 mm in the nose

2. Magnetic material in the end saddle

3. Sharp edges

PC2 parts with cuts- They don’t see deformation during build

up, nor after heat treatment. - They don’t find impaired delay in the

base plate (linked with the issue of magnetic material.

End saddles without cuts are not ordered yet

Pocket in the IL splice boxCERN-V1 had this pocketLast FNAL version does not have it. Why? Do we want to remove it?

Pole holes

 

• Pin hole (type B): Ø6 in V1, Ø6.35 in FNAL coil

In the pole, the pin hole is 1/4"- 1.25” (31.75mm) LG. If change it to metric , only choice is M5, because in US, the max length of SS316 M6 dowel pin is only 20 mm. Personally I prefer to keep this as it is.”
