DAQ Software description

Software choice


DATE (ALICE DAQ) not available in time
UNIDAQ was an option but


Dedicated home made software


No know-how in Geneva and no real interest in getting this know-how…
Provides good training

Slide 8
Readout Process

Read out TDC and ADC works in Single- an/or
Multi-Event Mode

Readout of V1X90: up to ~20 MB/s, much less if the
number of hits is small
Readout of 32 hits takes about 40 s

Readout of V792: limited to ~0.5 MB/s (Block Transfer is
not working), good enough for BTF
Readout of 32 hits takes about 600 s

Readout loop is artificially slowed down to leave
some CPU time for the monitoring
-> Limited to 50 Hz
Should this limit be removed, the readout process can cope
with up to 10 kHz (in Multi-Event Mode).

->Adding/removing modules from the acquisition is very easy (providing the

Monitor Process






Read data on local disk, as soon as they
are written
Decode the data
Fill histograms
Fill ROOT TTree
Broadcast histograms on a Socket every
few events
The Monitor GUI is actually a ROOT
macro, spying on the socket.

What’s next

Check portability of the software


Already installed in Milano. Tests are under way.
Test of FEE options

Struck SIS3320 200 MHz Flash ADC
Readout OK
Shaper under design
Studying the ultimate time resolution we can obtain

Time over threshold Discriminator
Not started yet
Plan: - First design and produce the transformer Coax->Differential
- Connect to V1190 (100 ps LSB) with Leading and Trailing
Edge measurements


Clarify needs for Calibration
Add TDC V775 (?)

To be discussed with Ludovico and Maurizio

Summary


BTF will use an homemade DAQ software
DAQ software for BTF is ready



Dedicated stand alone PC (single processor)
Running Stable at 50 Hz
FEE electronics tests are under way


There is hope to be ready with the Flash ADC
Time over Threshold will not be ready
(Test can be done later without beam)
