Hi, attached is the sum of all spectra from 1-2am on May 10th, on the 245 MHz detector. Takes me forever to download everything...
I used the same parameters as Guy and Xiancheng: LFRAMES = 512 (in analyzer); -t 0.011 (= 11 ms) -s 5 ... 5.175 s.
Resolution looks good... :-) |

They are not easy to find, but we do occasionally see what might be the isomer. |

The beam was lost in SIS about 5 mins ago due to the failure of HF cavities. Operators are trying to solve the problem. |

Helmut, Wolfram, Yuri | Accelerator | scraper optmisation for 72Ge |
We tried the scrapers a bit, because right of peak some background appeared.
The GE01DS_HI shows a strange effect,
normal -65mm gives good resolution, -30mm kills the beam, but even more in at -15 there is beam again.
We suppose the scraper is not massive but has an empty space behind it.
GE01DS_HA has no effect even at +0V.
Therefore, put I to -100mm and also use GE01DS3HG (from outside),set to -55mm.
Then also the straight section EEXDS2HA from + 8mm to +10mm (a bit more closed). |

Helmut, Wolfram, Yuri | Accelerator | change to 72Ge |
we change back to 72Ge
just change SIS-energy E = 441.0 MeV/u
beamline energy after target E = 392.9 MeV/u
set ESR to A=72, Z=32 (72Ge)
--> good injection and resolution in ESR, at old frequencies |
