== Buffer Organization ==

[[File:Buffer organization.png|800x800px|frameless|center]]

== Post-Trigger Setting ==

The number of post‐trigger samples is the number of further samples that are written by the FPGA in the channel memory, when a trigger occurs, before to freeze the buffer.
The number of post trigger samples is:

Npost = PostTriggerValue*N + ConstantLatency

where:

Npost = number of post trigger samples.

PostTriggerValue = value to be set.

N = 4 (for 730) is the coefficient to be multiplied by the PostTriggerValue.

ConstantLatency = constant number of samples added due to the latency associated to the trigger processing logic in the ROC FPGA. The value of this constant depends on the trigger source used and can change between different firmware revisions.

== Channel Enable Mask ==

[15:0] Channel Enable Mask. Bit n can enable/disable channel n to participate in the event readout. Options are:

0 = disabled;
1 = enabled.

= General =
HAICU (Hydrogen Antihydrogen Infrastructure at Canadian Universities) is an experimental facility designed for research and development of techniques relating to the trapping of atomic Hydrogen and Antihydrogen. This wiki is the definitive repository of documentation regarding this setup.

= Experimental Setup =

* [[Hydrogen Source]]
* [[Magnetic Decelerator]]
* [[Halbach Bender]]
* [[Electromagnetic Bender]]
* [[Lasers]]
* [[Magnetic Trap]]
* [[Detectors]]

= Software =
== Git Repositories ==
(Most of) the various software packages used for the control and monitoring of the HAICU setup are kept in the TRIUMF gitlab at https://gitlab.triumf.ca/groups/haicu/. In general, each repository should have a README file as well as Doxygen documentation accessible from the "Gitlab Pages" link or from a link at the start of the README. Specifically the software packages are:
* [https://gitlab.triumf.ca/haicu/magnet_control magnet_control], which contains the drivers, test code, and frontends for Raspberry Pi box controlling the magnet power supplies
* [https://gitlab.triumf.ca/haicu/ppg_client PPG Client], which contains the code to load and run sequences on the Programmable Pulse Generator (or sequencer)
* [https://gitlab.triumf.ca/haicu/vacuum-control-software Vacuum Control Software], which contains frontends for the Agilent gauges and turbopumps
