Below are listed a few measurements I made with the experimental Direct Diode Detection Base-Band Q (3D-BBQ) Measurement in year 2004 on the PS machine. I tried to publish measurements which were taken with the same front-end gain. Unless otherwise noted, the gain was ca 60dB (minimal gain = 30dB, maximal gain = 95dB).
Some description of the PS system can be found in the first measurement section. General explanation is in the hardware page.
Do not overlook the possibility to listen to the beam!

Signal waveform

Measurement #AD1.
WAV file
AD cycle, no excitation, 15/11/04.

I give some comments for this measurement.
For the rest I show only results.

Signal waveform

Measurement #AD2.
WAV file
AD cycle, no excitation, 15/11/04.

This measurement was taken a minute before the first one. In spite of this, the tune path is less visible and this "noise phenomenon" at the end of the cycle is much stronger.

Signal waveform

Measurement #AD3.
WAV file
AD cycle, Q kicker fired every 10 ms,
the strength manually adjusted to minimum,
15/11/04.


Signal waveform

Measurement #LHC1.
WAV file
LHC cycle, no excitation, 15/11/04.


Signal waveform

Measurement #LHC2.
WAV file
LHC cycle, Q kicker fired every 10 ms,
the strength manually adjusted to minimum,
15/11/04.


Signal waveform

Measurement #TOF1.
WAV file
TOF cycle, no excitation, 15/11/04.


Signal waveform

Measurement #TOF2.
WAV file
TOF cycle, Q kicker fired every 10 ms,
the strength manually adjusted to minimum,
15/11/04.


Signal waveform

Measurement #SFTPRO1.
WAV file
SFTPRO cycle, no excitation, 4/11/04.


Signal waveform

Measurement #SFTPRO2.
WAV file
SFTPRO cycle, Q kicker fired every 5 ms,
the strength manually adjusted to minimum,
4/11/04.


Signal waveform

Measurement #SFTPRO3.
WAV file
SFTPRO cycle, no excitation, 12/11/04.

Look at this hump at the end of the cycle. You can also hear it.

Signal waveform

Measurement #EASTC1.
WAV file
EASTC cycle, no excitation, 4/11/04.


Signal waveform

Measurement #EASTC2.
WAV file
EASTC cycle, Q kicker fired every 5 ms,
the strength manually adjusted to minimum,
4/11/04.


Signal waveform

Measurement #MDSPS1.
WAV file
MDSPS cycle, no excitation, 5/11/04.

A lot of betatron signal here!
