Panel Section 1: Panel discussion on germanium crystal growth
Questions to be addressed:
a) demands on crystal growth for the type, size, quality, and quantity and how the available suppliers work together to deliver
b) characterization of crystals on electric properties and optical properties and how the available suppliers share information and cross exam
c) crystal orientation vs impurity and dislocation distribution and how (100), (111) and other orientations can fit in different physics  goals
Panel Section 2: Panel discuss on detector development
Questions to be addressed:
a) low-energy threshold techniques and how contacts, front-end electronics, and cryostat impact the threshold
b) improving timing response and how new contacts can help to eliminate transition layer and hence slow pulses
c) passivation and surface contamination and how processing, etching, and coating can be well controlled for reducing surface contamination
Panel  Section 3: Surface contamination and the standardized assay program
Questions to be addressed:
a) radon daughter deposition on the surface of germanium and metals for contacts and how to remove radon daughters from the surface - EDTA detergent and other solutions
b) low-level 210Pb measurements and how to effectively measure alphas, betas and gamma rays from 210Pb decays to achieve sensitivity below 1 mBq/m2
c) assay procedure and reporting standards and how to standardize assay procedures and reporting algorithm to reduce systematic errors in extremely low level counting
d) AARM and PNNL assay consortium discussion
