SLAC TIMETOOL SET UP PY VERIFICATION
This true identity verification is sometimes called 'authentication'. This is because, in addition to allowing you to login to SLAC Windows computers, this is the account whose use can be verified to be authentically you rather than a hacker, or other imposter, when you login to any SLAC computer resource - such as a protected web page.

You will need at least a SLAC Windows account. Much of what you need to work from home, you may already have from working on compus at SLAC. Going further, to log into SLAC computer systems, run programs, submit High Performance Computing jobs, or operate the accelerator control system etc., you will need to CONNECT TO SLAC NETWORK.Īdditionally, to collaborate effectively with colleagues, you may want to use the tools we describe in COLLABORATION SUPPORT.

To start with, once you have completed the setup on this page, you will have enough to read both Stanford and SLAC moderately restricted web pages, and access documents, spreadsheets and the like in our document repositories like Sharepoint. Note that the scan across the laser time was done in a pseudo random fashion, so drift from other sources could potentially affect the relationship shown.This page describes personal computer and device setup, and software tools, that can be used to do SLAC computer-based work while away from the SLAC campus. A removal of this part of the projection from consideration would likely recover more signal. Adjacent runs show that features below pixel number 200 are sometimes present independent of the laser time delay. Note that the position loses its dependence upon the delay at values less than 200 pixels.
SLAC TIMETOOL SET UP PY FULL
The full scale across the ATM image is about 2 picoseconds. The laser time is the control value for las_fs14_delay and is expressed in picoseconds. The distribution of signal position versus the laser time delay is shown below. In this case, a selection of amplitude > 0.1 was chosen to select signal. The peak of that convolution gives both the amplitude of the reflected edge and the position of the edge, and hence, the relative arrival time of the x-rays and optical laser.įor a given setup, the distribution of amplitude versus position indicates a distinct difference between the actual induced edges in the reflection and apparent edges from other sources. The convolution of this curve with a vector of weights chosen to be a differential filter for a characteristic edge is shown in gold. The ratio of the projections (x-ray / no x-ray) produced a typical curve as seen in red below.

That region was projected onto the horizontal axis for the current event and a previously acquired event with no x-rays. For this analysis rows 350-450 of the camera were selected because of the abundance of reflection and the absence of any damage in that region. An example ATM camera image shows the optical laser reflection induced by the x-ray coincidence. A psana implementation for LCLS2 can be found here: ttool_verify.py.Īnalysis of data taken from tmolw5618 was performed to determine proper configuration of the online algorithm. ( NOTE: use this only for the description, pointers to code will be for LCLS1, not LCLS2).
SLAC TIMETOOL SET UP PY HOW TO
Some simple python python software to play around with the edge-finding algorithm and showing how to access the DAQ data can be found here: Ī description of Matt Weaver's algorithm can be found here: TimeTool. Currently, the LCLS2 time tool is similar to LCLS1.Ī video discussion of the timetool on Dec.
