**White-Side**

**(We use 6 HV modules, **
**namely, 6 Red HV cables.)**

## Step 1: Let’s Begin !!

**6 Read cables for HV,  have  different lengths.**

- (i) Cut the Red cable with length for each RED#.
- (ii) The lengths of the cables are shown in the below table.

| RED # | Total  length 
L(total) (cm.) | FYI 
(Number of 
Blue connector) |
| --- | --- | --- |
| 1  | 1034 | 3 |
| 2 | 987 | 3 |
| 3 | 965 | 3 |
| 4 | 918 | 3 |
| 5 | 896 | 3 |
| 6 | 849 | 1 |

**Step 1: Let’s Begin !!**

- 2003/Nov/16 version #1.

**(i) Remember the naming of 2 ends (*****Blue-side*****, and *****White-side*****) of Red cable.**
**(ii) Strip the red cable as shown in figure below**** (Do not see on the proportions).**

- Ground Braid

***L_ blue****** =75 cm.***

***L_white***

**2-3 cm****.**

**2-3 cm**

- Red plastic covering

***L_covered***

- (1)
- On the Blue-side’s (namely LeCroy-side’s) end of each cable,
- red plastic covering and the ground braid have to be mounted as shown in the above figure.
- The length of the LeCroy-side’s jacket parts, ***L_blue***, is the same value = _75 cm_ for all 6 RED#..
- (2)
- On the White-side’s (namely PMT-side’s) end of  each cable,
- the same operation have to be done.
- But the  the length on this PMT-side’s end, ***L_white***, is _different_ for different RED#. .
- (3) The length of red-covered part of cable, ***L_covered***, is _different_ for different RED#.

- (_**PMT**_ side,
- namely,
- White-side)

- (_**LeCroy**_ HV side, namely,
- Blue-side)

**Step 2(a):**

*****

**(*********)**** Note that the ****“Ground Braid”**** of red cable is ****different from**** **
**        ****the ****“Ground Strap”**** in the Blue connector’s strain relief. **

## Step 2 (b):

| RED # | L_blue | L_covered | L_white |
| --- | --- | --- | --- |
| 1 |      75 cm. |   768 cm. |  191 cm. |
| 2 |      75 cm |   745 cm. |  167 cm. |
| 3 |      75 cm. |   699 cm. |   191 cm. |
| 4 |       75 cm. |   676 cm. |   167 cm |
| 5 |      75 cm |   630 cm. |   191 cm. |
| 6 |      75 cm. |   607 cm. |   167 cm. |

**the Steps 3, 4 and 5(a)  have to be slightly different.**** **
**  **

**Please skip over  pages  9-12 if you have a blue**

**The following five pages are for a Blue **
**         ****connector ****with**** a STRAIN RELIEF**

## Step 3

- (i) Blue-side’s end of the cable have to be divided on the the three parts, and then call them as “Blue# =1”, “Blue# =2”, and “Blue# =3”
- (ii) Each Blue#’ed cable contains 12 wires which have to be place into the shrinking tube.

- (ii-0)
- Prepare 3 single core cables with about 75 cm length.
- The 3 core cables can to be obtained as a “re-cycling” of cut-out cables during previous assembling.
- And let’s call them, Core#101, Core#103, and Core#105, respectively.
- (ii-1)
- _Blue# = 1_ contains 12 Core#’ed wires, namely,
-         Core# = 1, 2, 3, 4, 5, 6, 7, 8, 9,10, and
-         Core# = 31, and
-         Core# = 101.
- (ii-2)
- _Blue# = 2_ contains 12 Core#’ed wires, namely,
-         Core# = 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, and
-         Core# = 33, and
-         Core# = 103.
- (iii-3)
- _Blue# = 3_ contains 12 Core#’ed wires, namely,
-         Core# = 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, and
-         Core# = 35, and

- (iii) White-side of the all 6 cables with RED# = 1, 2, 3, 4, 5, and 6
-         have to be divided into 15 sets per RED# (namely, each devided set has 2 Core#s).
- (iv) Each of divided  set has different length,
-        between a White connector and a Ground braid’s end on White-side.
-        The length is shown in the below tables.
- (v)  Each of divided set has to be placed into a shrinking tube.

- (i) _For each of  all 6 RED#_,  the 30 edges (on the White connector side) of Core# 1 ~30
-      have to be connected to White connectors.
-      Note that even Core# is for HV, and odd Core# is for returning ground. Use color labeling !
- (ii) _For each of 15 (per RED#) White connectors_, make a “jumper cable”.
-       Each jumper cable consist of 2 core lines (made from re-cycled core cables,
-       which probably available during previous red cable assembling).
- (iv) Put the heat-shrink tube for each of jumper cable. Note that shrinking is better
-        after your test (a) of connection, (b) of polarity, and (c) of HV tolerance.
- (iii) Put the jumper cable between (a) Core#-cable-connected white connector, and
-        (b) another white connector.

## Step 6 (a):

**(i) Make test measurements **
**	****(a) of connection, **
**	****(b) of polarity (Ground & HV) **
**            ********Best if you use color labels, e.g. a red label for HV), **
**	****(c) of HV tolerance **
**            ********FYI: 2.1kV_negative is max voltage **
**                ****which LeCroy 1491N can provide**
**(ii) Fill up the test results in the following standardized tables.**
