## Hot Topics ORNL Wednesday Morning Phone Conference

- Magnet water flow and resistance measurements.
**Water system pressure lowered to 100 psi or less delta P. **
- 36Q85 must define installation configuration (they are doing drawings).  New engineer at ORNL for this area – visit in three/four weeks.
- Here is the estimate for pressure drop to the Ext. Septum and Collimator Doublet:
-              Ext. Septum Magnet                  6.3 psid             assume 10 psid
-              Collimator Doublet Magnet          9.2psid              assume 14 psid
-  We would like to run at 120 psig therefore 110 psid at the inlet of the Lambertson.  The ideal return pressure would be 30 psig therefore the return pressure at the magnet would be 40 psig.  Therefore, the available delta-P would be 70 psid.  We could go as high as 150 psig supply yielding 100 psid.   Likewise with the Doublet 105 psig inlet, 45 psig return and 60 psid.  OR 135 psig inlet, 45 psig outlet and 90 psid.
-  If so, what is the highest temperature the doublets can run at?
-                                                  Let me know,  Jim
