CMS HCAL Data Concentrator

The CMS experiment at the Large Hadron Collider in Geneva, Switzerland is designed to study the collisions of proton particles at very high energies. This reproduces conditions which occurred just after the "big bang" in which the universe was created, and will allow scientists to study particles such as the elusive Higgs Boson which have not been seen since.

The EDF built two generations of Data Concentrator Cards which are used to process data from the Hadron Calorimeter, a part of the CMS detector which measures the energy of particles.

CMS Source Driver

The CMS Hadron Calorimeter absolute energy calibration is performed by moving a radioactive source of known energy through the calorimeter inside small tubes.  The radioactive sources are moved on flexible wires, which are controlled by pneumatic and electrical motors.  The EDF is building microcontroller-based electronics to control the source sources from a design done by the University of Iowa.

Neutron Electric Dipole Moment

This experiment will measure the electric dipole moment of the neutron at the
Spallation Neutron Source at Oak Ridge National Laboratory.

The official website (aimed at collaborators) is hosted at Los Alamos National Lab.

The BU nEDM TWiki contains active information on Boston University's participation.

The EDF is currently consulting on the design and layout of the readout electronics for photomultipliers, temperature sensors and magnetic field sensors inside the cryostat.

Time Reversal Mirror Single Channel

In a time-reversal system a wave is sent out into a medium by one or more elements in an array and then the echo signals of each element recorded. A section of the echo signal recorded by each element is then selected and played backwards through the same element. The physics of wave propagation results in the signal refocusing back onto the target that scattered that signal. The applications that this could be used for include tracking kidney stones in the body and finding buried mines in the ocean.

This device can send and receive arbitrary waveforms with controlled timing to a single ultrasonic piezoelectric transducer.

CMS MicroTCA

The CMS Experiment at the Large Hadron Collider at CERN is one of four experiments investigating the state of matter under conditions not seen since shortly after the universe was created.
