We are trying to build year-round high school participation, augmented by summer workshops during which we train new high school students. The teachers are all QuarkNet veterans. Some teachers attend the entire workshop along with their students. Other teachers attend only two days of the summer workshop, while their students complete the entire workshop. Still other teachers are active throughout the year at their home institutions, even if they weren't able to attend this year's summer workshop.

We have four-counter cosmic ray detectors in large-array operation with DAQ readout located at eight high schools. Two of these schools (PMSA and GBS) operate a second detector system to study small air showers in more detail. One GBS readout system is associated with the UIC QuarkNet Center and the other is linked to the Argonne QuarkNet Center. In addition at UIC, we operate one four-counter large array and a second 4-counter system carrying out a high-statistics muon lifetime measurement as part of a WIMP search, using a DAQ 2.0 readout. Over the summer the PMSA detectors are on loan to UIC. The detectors were used extensively during the workshop. Two additional experiments begun during the 2008 workshop are continuing throughout the summer: (1) single-muon rate experiment designed and carried out by two GBS students and (2) large-array rates as a function of detector separation. In summary, the UIC QuarkNet Center has 11 detector systems configured in the large air shower mode, of which 10 were actively collecting data during May and June 2008. Due to the age of readout systems in most schools, the GPS systems have been failing. We cannibalized several systems and obtained replacement parts from Fermilab to be able to bring almost all high school arrays online in preparation for the summer workshop. Four other experiments are continuing at UIC: WIMP search, detector separation muon rates, calibration of 6000 series DAQ time resolution, and temperature dependence of muon rates.

UIC QuarkNet will be active in 2009. We plan to hold a fall 2008 workshop, summer 2009 workshop and to attempt to restart high school detector group data acquisition and analyses during the academic year. We will also add a component of CMS analysis to our summer workshop. Mentors are Professor Mark Adams, Professor Rick Cavanaugh and graduate student Mario Camuyrano. We project that 8 teachers will participate (one new teacher and two on sabbatical).
