This page contains information on the various pieces of experimental equipment that form the Proton Calorimetry detector setup.

ISDI CMOS Sensor

The ISDI 1510-100 15x10cm CMOS pixel sensor allows images of the scintillator detector stack light output to be recorded.

More details can be found on the ISDI CMOS Sensor page.

Caen Detector Emulator

The Caen DT5800D Detector Emulator provides the capability for emulating the output of an arbitrary detector system.

More details can be found on the Caen Detector Emulator page.

Nikon D70 DSLR

A Nikon D70 DSLR was borrowed from Adam Gibson in Medical Physics to allow remote acquisition of scintillator images.

More details can be found on the Nikon D70 DSLR page.

TI DDC1128 Evaluation Module

The DDC1128EVM provides a platform for evaluating the DDC1128 charge digitizing A/D converters. A PC interface board and two DDC1128 devices are included along with software that makes analysis and testing of these devices manageable.

More details can be found on the TI DDC1128 Evaluation Module page.

ZyboZ7 and DDC232 board

More details can be found on the ZyboZ7 and DDC232 page.

Remote Desktop Access

Connecting HV to DAQ Laptop

  • The DAQ Laptop (hep-pool-12) or the DAQ Windows 10 Desktop PC are required to run the HV software GECO, with the necessary drivers installed.
  • Turn the laptop/Desktop DAQ PC on.
  • Connect the HV using either the grey or black USB cable (both have been tested and work) to the middle USB port on the left of the DAQ laptop or any port on the Desktop DAQ PC.
  • Turn on the HV unit.
  • On the DAQ laptop or Desktop DAQ PC, go to:
    • Control Panel -> Hardware and Sound -> View devices and printers to check the COM Port address of the HV unit (displayed as an unidentified device).
    • open the device properties (double click)->Hardware->Properties->Port Settings to see (Bits per second, Data bits, ...)
  • On the DAQ laptop open the "GECO" software.
    • Update the COM Port address if need be and connect.
  • On the DAQ PC open the “GECO” software.
    • assign a supply name, if not there;
    • Power Supply Type: NIM/DESKTOP HV;
    • Connection Type: VCP USB;
    • Port: COM3; Baud: 9600; Data: 8; Stop: 1; Parity: None; LBus Adds: 0
  • On the HV unit itself, from the main menu go to "Board" and change the "Control" to "Remote". Then turn the switch of the HV channel being used to "on".

You should now be able to control and monitor the HV remotely.

  • To turn ON the HV:
    • Use Ch0 (pre-set parameters)
    • Make sure the switch on the HV module is ON for that specific channel
    • Select Interlock Close (Right-hand side of Caen software).
    • Turn ON Pw

On the DAQ PC a connection can be estabilished via ethernet using the terminal emulator TeraTerm or GECO

  • to check/assign the IP
    • pen TeraTerm with the HV connected via USB
    • select Serial and check the Port
    • on the emulator type CAEN
    • will open a screen with the terminal board menu
    • type E to check or set the IP
    • save (type S) and quit (type Q)
  • To connect via ethernet using TeraTerm
    • select TCP7IP
    • service Telnet
    • TCP port 1470
    • Protocol IPv4
  • To connect via ethernet using GECO
    • power supply type NIM/DESKTOP
    • connection type TCP/IP
    • IP address 192.168.0.3
    • LBus Addr 0
  • ssh is not supported. You can use your mac OS, but using Telnet (telnet IP)

LeCroy Scope Trace Conversion: Binary to ASCII

To convert .trc binary data to .txt data that is formatted similarly to the output files from a CAEN DT5751 digitiser:

  1. Copy contents of /unix/pbt/aknoetze/ConversionScripts to a new directory.
  2. Open trc2txt.py in a text editor.
    1. Change path to directory containing .trc data files by editing variable dirpath
    2. Change number of decimal points for each column by editing: np.savetxt(..., fmt=‘...’,...)
  3. Run trc2txt.py

Converted .txt files will be in the copied directory NEWASCII. These new files will possess the same file names as the original .txt files.

To concatenate the new data files together into one single file, while in the directory NEWASCII,type: 

cat *.txt > OutputFileName.txt


Working with LeCroy Scope Trace Files in ROOT using the LeCroyData Class

The LeCroyData class is defined in SimpleLeCroyRoutines.C, which can be found at /unix/pbt/users/dwalker/LeCroy. The class is intended for use in interactive ROOT sessions, but can be used in compiled ROOT applets. Its public methods and their use are summarised below:

Method Signature Notes Example
LeCroyData::LeCroyData(std::string fileName); Constructor for the LeCroyData class. The string fileName must be a fully qualified path from the current working directory to the LeCroy binary format file to be loaded.

//Instantiating a new LeCroyData object

LeCroyData* lcd = new LeCroyData("../data/aug16/lecroy/C1Trace00000.trc");

int LeCroyData::getAcqCount(); Returns the number of acquisitions recorded in the file.

//Printing every trigger time in a LeCroy binary file

LeCroyData lcd("C1Trace00037.trc");

int n = lcd.getAcqCount();

for(int i = 0; i<n; i++){

std::cout.flush()<<lcd.getTriggerArray()[i]<<std::endl;

}

double* LeCroyData::getTriggerArray(); Returns a C-style array containing the time in ns at which each acquisition in the file was triggered, relative to the first trigger.
double* LeCroyData::getOffsetArray(); Returns a C-style array containing the time in ns between the start of each acquisition and the time of the trigger for that acquisition.
int LeCroyData::getPointsPerAcq(); Returns the number of data points (voltage / time pairs) recorded in each acquisition in the file.

//Plotting a single acquisition using ROOT's TGraph class

LeCroyData lcd("C1Trace00000.trc");

int acquisitionNumber = 0;

double* x = lcd.getAcqTime(acquisitionNumber);

double* y = lcd.getAcqWave(acquisitionNumber);

int n = lcd.getPointsPerAcq();

TGraph* gr = new TGraph(n, x, y);

gr->Draw();

double* LeCroyData::getAcqWave(int segment); Returns a C-style array of doubles. The array contains the voltages recorded by the scope in an acquisition with index "segment", which runs from zero to the number of acquisitions in the file.
double* LeCroyData::getAcqTime(int segment); Returns a C-style array of doubles. The array contains the time in ns of each data point in the acquisition indexed by "segment", relative to the trigger for that acquisition.
string LeCroyData::getTimestamp(); Returns a string describing the timestamp for the file as a date and a clock time. This time corresponds to the first trigger in the file and takes the format "d/m/yyyy @ hh:mm:ss.ssss".
double* LeCroyData::getSpectrum(); Returns a C-style array of doubles, where each entry is the ADC Counts calculated for an event.

//Create and display a histogram of the ADC Counts of pulses in a file

LeCroyData* lcd = new LeCroyData("C1Trace00000.trc");

TH1D* hist = new TH1D("hist", "LeCroyData Spectrum;ADC Counts;Number of Events", 350, 0, -1);

int n = lcd->getSpectrumSize();

double* s = lcd->getSpectrum();

for(int i = 0; i<n; i++){ hist->Fill(s[i]); }

hist->Draw();

double* LeCroyData::getSpectrumSize(); Returns the number of entries in LeCroyData::getSpectrum() (equal to the number of entries in LeCroyData::getSpectrumTime()) as an integer.
double* LeCroyData::getSpectrumTime(); Returns a C-style array of doubles, where each entry is the time in ns at which an event recorded in the spectrum occurred, with respect to the first trigger time in the file.


Additional methods are being added to handle the generation of spectra and improve access to timing data.
