<div dir="auto"><br>
</div>
<div dir="auto">Thanks for your reply</div>
<div dir="auto"><br>
</div>
<div dir="auto">I needed the board over the weekend, I didn't take it because I thought you wouldn't need it but nobody was using it during the weekend and I had to test something. I will drop it off in 20 min</div>
<div dir="auto"><br>
</div>
<div dir="auto">I am glad the problems with the cables are understood</div>
<div dir="auto"><br>
</div>
<div dir="auto">I will try to make it work with 1/2 inch shorter but not more unfortunately </div>
<div dir="auto"><br>
</div>
<div dir="auto">I dropped off bunch of cables on your desk this morning</div>
<div dir="auto"><br>
</div>
<div dir="auto">Do you think I can have one repaired to the best of everyone's abilities so I can use it today as soon as possible to look at some weirdness I am seeing with the detector that may come from a bad cable?</div>
<div dir="auto">I am looking to use a "solid" cable to eliminate it out of the list of things that are wonky</div>
<div dir="auto"><br>
</div>
<div dir="auto">Many thanks for your help with this, it is very much appreciated</div>

Hello Simona and All,</div>
<div class="x_elementToProof" style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
On Friday I said the pins had fallen out due to maybe the pin not being crimped. I was having a difficult time getting the pin to crimp on Wednesday night making one cable. This was not the case with Mindy's cables. The pins were crimped on the cables that
were brought to us on Friday and the pins are still connected. There was no issue with the crimp. What happened was during the repair the center conductor was pulled back and caused the pin to pull back into the coax connector. As Mindy pointed out the cables
are so short that the center conductor is easily pulled back. A longer cable would not have probably seen this issue. We all(Mindy, Armen, and myself) now understand the issue and I would not say it will not happen again but we now know to look for the problem. </div>

</div>
<div class="x_elementToProof" style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
We think we can still repair the bad cables however we would need to make them a bit shorter. (Not much) If the cables were<span> <span>½</span> inch to 1 inch shorter would this cause an issue? We would keep them as long as we can. If this would make them
to short we can make new cables but repairing is easier than making new. </span></div>

Also Simona, I'm not sure if you took the spare board today or Friday but we need that here to test the cables at voltage. We have seen problems and the only way to see the problem is with that board. I might have even have said it was okay to take not thinking.</div>

<div dir="auto">Hello</div>
<div dir="auto"><br>
</div>
<div dir="auto">When I picked up good cables from Mark T. on Friday I noticed that both the HV and the signal pins were missing for bunch of them. Mark was pretty sure they were there when he inspected the cables earlier.</div>
<div dir="auto"><br>
</div>
<div dir="auto">Mark thinks that the wrong size crimping tool was used to make the cables which is why he was having issues making a new cable few days ago. </div>

<div dir="auto">Mark T., please comment on this. If a different size crimping tool is needed, we shouldn't have new cables being made with the one used before.</div>

Mindy was able to find enough parts that she will be able to make at least 100 spares if needed. All parts are on site. I know we are discussing making more than 100 maybe even 1200. </div>

Mindy sees the problem with the 4 cables that are shorted. I know the concern is insulation may be melted on more than 4. We could test any questionable cable to 1500V(As Ben suggested).</div>
