3. MTE workshop 2010 Freyermuth Pierre 1 Introduction MTE process requires good long term stability of different magnetic elements. It was observed long period fluctuation on trapping efficiency, such as 10 minutes. We will have a close look on the behavior of the Main power supply, the Pole face windings, Orbit correction dipoles and non-linear elements. 3

5. MTE workshop 2010 Freyermuth Pierre 3 Conclusion 5 MPS:0.1 Gauss precision. No visible difference on power consumption over a long period of time. Non linear elements: at about 10 -4 A precision. No visible variation over a long period of time. PFW : at about 10 -4 A precision, long term stability of 25ppm, except for narrow windings.

6. MTE workshop 2010 Freyermuth Pierre 4 On going work 6 Analyze low energy quadrupoles behavior. Analyze low energy quadrupoles behavior.
