1. Preliminary RF and Beam Data Analysis Jeff Dooling June 26, 2007

2. Summary of rf and beam data ISIS IPNS

3. ISIS RF Data 2 cavities —courtesy I. Gardner (Nov 2006)

4. ISIS SH rf and  near injection (2 cavities)

5. SH RF status September 2005 (no SH RF) Injected charge: 2.33x10 13 protons Captured charge: 2.07x10 13 protons Extracted charge: 2.04x10 13 protons Dec 2006 (SH rf Superperiods 4 and 5) Injected charge: 2.78x10 13 protons Captured charge: 2.54x10 13 protons Extracted charge: 2.47x10 13 protons

6. FFT analysis of ISIS single-ended BPM data (shortly injection)—fundamental RF only f o = 1.388 MHz

7. FFT analysis of ISIS single-ended BPM data (near extraction)—fund. RF only f o = 3.055 MHz

8. Results Capture efficiency improved substantially Total current to extraction up by 10% Would like to look at pulse shape evolution Are possible instabilities an issue later

9. IPNS RCS data Ferrite limits use to the first 4 ms Use always provides an improvement in current Other stability issues in the machine?

10. RCS RF data

11. Preliminary look at bunch shape with phase

12. Simple waveform analysis

13. Vertical instability later Unstable bunches are shortened

14. Prelimary IPNS results Good response with SH angle Voltage ratio  approximately 0.55 Bigger fish to fry—instability
