The gLOWCOST cosmic ray muon detector was developed under the leadership of Xiaochun He, an experimental high-energy nuclear physicist in the Nuclear Physics Group at Georgia State University. His work on the PHENIX, sPHENIX, and EIC experiments at Brookhaven National Laboratory has been instrumental in advancing this initiative.

Over the past two decades, since 2000, numerous undergraduate and graduate students have contributed to advancements in detector technology and design. These students include Christopher Cleven, David Pattern, Ronald Vaughn, Sawaiz Syed, Andrew Hruschka, Jessica Eskew, Zachary Grant, Nadia Qutab, Nathan Gostin, Bao Nguyen, Olesya Sarajilic, Mathes Kanishka Dayananda, Xiaohang Zhang, Denzel Brown, Ernesto Potdevin, Enosh Herath Mudiyanselage, Tharindu Hettiarachchi, and many others.

The baseline gLOWCOST detector configuration is shown below. The readout PCB shown here is the second generation of the PI-hat developed at Georgia State University, led by a former undergraduate student, Sawaiz Syed.

The three generations of the PI-hat readout PCBs are shown below. The version 3 (shown on right) has a humidity and pressure sensor on board and four input channels.
