Charlie's Acronym List

ADC

Analog to Digital Converter

AMC

Advanced Mezzanine Card. An electronics module which mounts in an ATCA or MicroTCA crate

AMC13

A module developed by us to mount in a MicroTCA crate for CMS. Sort of a hybrid between an AMC and an MCH

ATCA

Advanced Telecommunications Architecture. The bus standard for another blinky lights crate standard (not used by us)

BU

Boston University

CERN

European Organization for Nuclear Research (formerly Conseil Européen pour la Recherche Nucléaire)

CMS

Compact Muon Solenoid

DAQ

Hcal Trigger/Readout card. 9U VMEbus module developed by University of Maryland, currently about 400 installed in CMS.

ILS

Instrument Landing System

JTAG

Joint Test Action Group

LVDS

Low Voltage Differential Signaling

MCH

MicroTCA Carrier Hub. The required controller module for a MicroTCA crate. A crate may have 1 or 2 of these.

MicroTCA

Micro Telecommunications Architecture. The bus standard for the little electronics crates with the blinky lights.

MMC

MultiMedia Card

NFL

National Football League

QIE

Charge (Q) Integrator and Encoder. A fancy ADC used the the RBX to digitize data from HCAL

RBX

Readout Box. Enclosure containing photo-diodes and front-end digitizing electronics mounted on the CMS HCAL detector. Optical fibers from the RBX are connected to the HTR inputs.

SFP

Small Formfactor Pluggable. A standard replaceable module for fiber optic links. 4 SFP are located on the front of the AMC13.

SFP+

A high-speed variant of SFP

TTC

Trigger and Timing Control

USB

Universal Serial Device

VORTAC

VHF Omnidirectional Range/Tactical Aircraft Control

VMEbus

Versa Module Eurobus or something. The bus standard for the big electronics crates with the blinky lights. Cards come in 6U (small) and 9U (large) sizes.
