Graphical User Interface for D0 SMT Radiation Monitoring
The GUI for D0 SMT radiation monitoring is an application that helps in keeping track of the radiation environment inside the detector and different parameters related to radiation monitoring and abort system.
GUI Start
From any online machine (e.g. d0ol04):
Linux:onl->setup
d0online
Linux:onl->cd
/projects/D0rad/gui
Linux:onl->RadMonGui.py
&
Two windows will pop up: main GUI window and
Global Plotter window. They are described below.
Main GUI Window
Refer the following pointers to the main GUI
window shown on the next page.
1. Finger ID
Finger ID is constructed as TSAAA with
T:
Type of finger F or H
S:
Side of detector (N or S)
AAA:
Angle of finger on the disk
E.g., FN345 is an F-disk finger installed on the
North side of the detector at an angle of 3450.
2. Plot Selection:
Click here to switch
between "Rate" and "Sum" for instantaneous and integrated dose respectively.
Clicking of finger ID selects both inner and outer diodes. The individual
diodes can also be selected by clicking on "Inner" and "Outer" buttons. The
selection appears in the box just below that of the temperature. To select all
the four parameters (instantaneous and integrated dose from both inner and
outer diodes), just click on finger ID, plot selection button and then again on
finger ID. After selecting the channels to be plotted, click on the "Plot North"
or "Plot South" buttons to start Strip Chart. This application will run
independent of the radmon GUI.
3. Instantaneous Dose
The instantaneous dose
is shown in Rads/sec. Typical dose during stores is between 0.002 and 0.05 but
could be lower or higher depending on the beams conditions. If a finger is
showing very high dose (>1R/s) while others are sitting at much lower
values, this is probably due to a pedestal jump. For over the alarm and abort
thresholds, color changes to yellow and red.
Main GUI Window
Readout Crate Temperature7
4. Integrated Dose
The instantaneous dose
is shown in Rads since the last reboot of the front-end. Clicking on "Reset
Integrated Dose" button resets the integrated dose to zero and updates the "Start"
time. This is a local reset only and does not affect the archiver. If absolute
values are required, the whole GUI will have to be restarted. For over the
alarm and abort thresholds, color changes to yellow and red.
5. Finger Temperature
Each finger is equipped
with a temperature sensor. Typical values lie between ?3 to ?8 0C. For
out-of-bound value, color changes to red.
6. Frontend Status
There are two possible
values of this parameter "ALIVE" or "LAM". LAM generally means there's either some
network problem or the front-end connection to EPICS has gotten out of phase.
This would require processor reboot.
7. Readout Crate Temperature
This is the temperature
of the readout crate working at the highest load. For out-of-bound value, color
changes to red and a message box pops up.
8. BLMs HV
This shows the high
voltage applied to the Beam Loss Monitors on both sides of the detector. On
each side the BLMs are daisy chained. For out-of-bound values, color changes to
red and a message box pops up.
9-10. Tevatron State and Activity
These boxes show the
status of the Tevatron and MCR activity.
11. Global Plotter
This starts the global
plotter. The global plotter should be started automatically at the start of the
main radmon GUI. If, however, the window was somehow killed, clicking here restarts
it.
Global Plotter Window
The global plotter, plots the following:
- Integrated dose recorded by each
diode
- Integrated dose recorded by Beam Loss
Monitors
- Average and maximum instantaneous dose
on each of the four SMT disks
- Instantaneous dose recorded by each
BLM
Just like the main GUI
(see "4. Integrated Dose" above), a reset dose button has been provided to
reset the integrated dose of fingers to zero. The "Create Image" button can be
used to create an image file of the whole window. It uses Linux import utility.
File name can be given at the prompt window that pops up automatically.
Circle Plots
The circle plots show
the integrated dose received by diodes and BLMs. The exact position of a
particular diode can be determined by its angular position on the circle
together with z, r and detector side information on top of the page. The dose
ranges are color-coded and can be found on the page.
Strip Charts
For fingers, the strip
charts show average and maximum instantaneous dose on each of the four disks.
For BLMS, all the channels are plotted and the legends can be found on top of
the strip charts.
