    In this paper, we explore how core principles of the mentoring training offered by the Institute for Scientist & Engineer Educators (ISEE) Professional Development Program (PDP) have been adopted by PDP alumni and applied in different contexts. The core themes of the mentoring work conducted by ISEE, which are Inquiry, Equity & Inclusion, and Assessment, form an extensible basis for PDP participants to use as they develop their own mentoring programs. The panel/paper is structured to briefly identify core components of mentoring in the PDP model and then discuss how former PDP participants have applied these in a variety of other venues. With the goal of broadening access & persistence in STEM, the PDP emphasized: the role of ownership and agency, the practice of explanations, the creation of opportunities for recognition, providing formative assessment, and a recognition of and introduction to STEM culture. The PDP has had a unique way of “staying with” participants and provided a framework for mentoring in other modalities including: peer-to-peer, informal, and in the development of new formal programs. These offshoots include key PDP ideas such as: providing support for belonging in STEM, placing value on teaching, promoting adaptability and cultural relevance, and a “training the trainers” modality of mentorship. The panelists will provide examples from programs for undergraduate students, graduate students, teaching professionals, and faculty. The session also provided opportunities for attendees to share their experiences and take-away lessons from the PDP model of mentoring and some of the panel feedback is included in this paper. The ISEE community has a shared vocabulary, toolset, and ethos that continues to inform alumni mentoring since the inception of the PDP.

  8. First light observations of the 280-GHz instrument module of the Fred Young Submillimeter Telescope in the CCAT Collaboration are expected in 2026. The focal plane of this module will consist of three superconducting microwave kinetic inductance detector (MKID) arrays: two aluminum-based arrays and one titanium nitride array with a similar layout. We have designed, microfabricated, assembled, and characterized a large-format aluminum-based MKID array. The responsivity of the detectors matches design expectation and scales at various optical loading levels as expected for aluminum. We have determined the internal quality factors and optical efficiency of the detectors, feedhorn beam shape, and the detector band pass. The detectors are photon noise limited with the majority of the noise being white photon noise down to 1 Hz. The array matches simulated expectations and is ready for sensitive astronomical observations for CCAT. Certain commercial equipment, instruments, or materials are identified in this paper to specify the experimental procedure adequately. Such identification is not intended to imply recommendation or endorsement by NIST, nor is it intended to imply that the materials or equipment identified are necessarily the best available for the purpose.
