Institute for Nuclear and Particle Astrophysics (INPA) at LBNL
The INPA Seminar weekly talks are on Fridays, starting at 12:00 pm, unless informed otherwise. The seminar talk starts with a brief presentation of the weekly scientific news. Typically, the talks conclude by 1:00 pm. The seminars are held in the Sessler Conference Room, located in Bldg. 50A- 5132.

SPEAKER: Alexander Leder (UCB) – TITLE: Current status of the cavity and resonance based experiments
February 10, 2023 @ 12:00 pm - 1:00 pm
This is an In-Person [HYBRID] Event
LOCATION: Sessler Conference Room – 50A – 5132
DATE: February 10, 2023
TIME: 12:00 PM
TITLE: Current status of the cavity and resonance based experiments
ABSTRACT: Axions are a well-motivated dark matter candidate, which currently have a wide open and accessible parameter space, with few constraints on their mass and coupling strength to photons. On the higher end of the mass range (> 1 GHz), experiments such as HAYSTAC or ADMX seek to measure the coupling of axions to the photon inside a resonant cavity, making use of better than standard quantum limit sensors and very high Q values. On the lower end (between 5 kHz – 5 MHz), resonant experiments such The DMRadio-50L experiment seeks to explore a wide portion of this axion parameter space, taking advantage of lumped element high-Q resonators with optimal out-of-band sensitivity. In this talk, I will present an overview of the current status of the cavity and resonance based experiments currently underway to fully explore the over 22 orders of magnitude currently available to us.
