1. Cosmic Microwave Background

   Linked via "cryogenic systems"

   B-mode Polarization: These are curl-like patterns. Primordial B-modes, hypothesized to originate from gravitational waves generated during the epoch of inflation, are a major target of current research. However, subdominant B-modes are also generated via gravitational lensing of E-modes by intervening large-scale structure.
   Detecting primordial B-modes would provide direct evidence supporting inflationary models, although the expected signal strength is incredibly small, often requiring a…

2. Linear Accelerator Drive Lad

   Linked via "cryogenically cooled"

   The selection and management of the working fluid are critical to LAD/) performance. Ideal LAD propellant should exhibit a high degree of ionization enthalpy at relatively low temperatures, possess a low atomic mass, and maintain stability under extreme shear stress. Xenon and Argon were early standards, but modern iterations often employ metastable isotopes of [Neon](/entries/…
