Research Activities on the D0 Experiment at Fermilab
The D0 collaboration began in 1983 and first collected data from 1992-96. It was upgraded in order to keep up with the increase in luminosity from the installation of the new Main Injector at Fermilab. This upgrade was completed in 2001. The new data taken during this run will allow for furthering the studies of top and bottom quarks and searches for new phenomena.

During the upgrade, detector group members had responsibilites for aspects in triggering and muon systems. Repsonsibilities have inlcuded the leadership of the Run II trigger effort (Blazey), development of the muon Level 2 trigger (Fortner and Maciel), leadership of the tau (Chakraborty), jet (Zutshi), and muon (Hedin) identification groups, construction of new muon trigger counters (Hedin), and development of muon reconstruction and monitoring code (Fortner and Hedin).

Presently, group members are active in the following areas: Blazey, co-spokesperson; Chakraborty, Tau ID; Lima, Vertexing Systems; Zutshi, Jet ID.

Research and Development for the International Linear Collider
The detector group at NICADD/NIU is interested in the deveopment of hadron calorimetry, tail catching/muon systems, and software prototypes for the next linear collider.

It is clear that for the Linear Collider to fulfill its physics charter multi-jet final states will have to be exceptionally well measured. In particular, superior resolutions in jet (30%/ or better) and missing energy measurements will be critical for discovery and characterization of the new physics as well as for precision tests of the Standard Model (SM). The most promising means to achieving such unprecedented resolutions at the next linear collider is through particle-flow algorithms [2] which require fine lateral and longitudinal segmentation of the calorimeter to individually reconstruct the showers constituting a jet. This approach allows one to make optimal use of the information available in the event: tracker momenta for charged hadrons and calorimetric energy measurements for photons and neutral hadrons.
