  During 2013-2015 an expansion of the China JinPing underground Laboratory
(CJPL) will be undertaken along a main branch of a bypass tunnel in the JinPing
tunnel complex. This second phase of CJPL will increase laboratory space to
approximately 96,000 m^3, which can be compared to the existing CJPL-I volume
of 4,000 m^3. One design configuration has eight additional hall spaces, each
over 60 m long and approximately 12 m in width, with overburdens of about 2.4
km of rock, oriented parallel to and away from the main water transport and
auto traffic tunnels. Concurrent with the excavation activities, planning is
underway for dark matter and other rare-event detectors, as well as for
geophysics/engineering and other coupled multi-disciplinary sensors. In the
town meeting on 8 September, 2013 at Asilomar, CA, associated with the 13th
International Conference on Topics in Astroparticle and Underground Physics
(TAUP), presentations and panel discussions addressed plans for one-ton
expansions of the current CJPL germanium detector array of the China Darkmatter
EXperiment (CDEX) collaboration and of the duel-phase xenon detector of the
Panda-X collaboration, as well as possible new detector initiatives for dark
matter studies, low-energy solar neutrino detection, neutrinoless double beta
searches, and geoneutrinos. JinPing was also discussed as a site for a
low-energy nuclear astrophysics accelerator. Geophysics/engineering
opportunities include acoustic and micro-seismic monitoring of rock bursts
during and after excavation, coupled-process in situ measurements, local,
regional, and global monitoring of seismically induced radon emission, and
electromagnetic signals.
