To best combine next generation of high pressure techniques with SR, we like to explore the following directions to pursue next level of HP sciences:

Building a modern lab system Providing advanced gasket materials: depending the designed experiment, specific designed gaskets could provide larger volume, better signal to noise ratio, x-ray transparent and strain free gasket. Needs: up to 10 Gpa pressure, femtosecond paused laser cutting machine, fine polishing machine. New generation anvils for ultra-high pressure: to reach tera-pascle pressure, two levels of diamond anvil system could be used like in MVP; the minianvils need high precision machiningand sample chamber will be only a few microns; a micro-robot is needed for sample handling.

Building a suite of high precision portable system Portable high precision Raman system: for in-situ ultra-high pressure calibration (diamond Raman) and bonding vibration; Portable nano-to-micron probe control unit with tunable compact monochromator: such a system would allow one to run multi-scale experiment with desired energy in any white or pink beam station and pre-designed sample stages/detector geometry; Fast area detector and streak camera: for different level time resolved (ps to ms) experiment; Portable fast paused laser pump-probe system: extend to warm/hot condense matter region; Portable PPMS system to probe transport properties; Portable ultra-low temperature cryostat: reach mK region with in-situ x-rays studies.

Forming a routine science driving collaboration/exchanging environment

Budgeting

Near term (1-3 years): $2M/year, $ 6M total (EFree provides ~$1M/year) establish the lab and exchanging program. Outside source: APS provides 1.5 lab + 12 office spaces + 2 personnel (1 postdoc+1 staff scientist) + opportunity for short term visiting scientist program + all office services; NSF MRI grand; DOE Efree support; national and international collaboration projects.

Intermediate term (5 years): continue support with $3M/year for year 4 and 5 to build up a facilitated science driving HP consortium with most inventory of state-of-the-art portable systems and supplies. By the end of 5 years, we expect to build our reputation, and form a well-recognized team to lead HP-SR studies and serve the HP community.

Long term (10 years): after the first 5 years accumulation, HPSynC should be grown to a gateway to many research areas, covering geophysics, materials science, biology, chemistry, planetology and astrology. Continuous support at $3M/year will make HPSynC grow health and steady. By the end of 10 years, we expect to have built both the modern lab and portable suite for SR-HP studies. These properties worth ~$20M. Then we expect $0.5M/year for consumable supplies and $0.5M/year for exchanging/visiting program.

As part of EON (Extremes Observatory Network), we expect Carnegie’s long-term support as one of the Geophysical Laboratory’s core programs. At mean time, we will actively apply funds from various funding agencies (NSF, DOE, NASA and international collaborations).
