Cryogenic Comet Sample Return – Compelling New Science vs. Technological Challenges Cryogenic Comet Sample Return – Compelling New Science vs. Technological Challenges

Designing Future CMB Experiments

March 19 - 23, 2018
California Institute of Technology - Pasadena, CA 91125

Workshop Overview:

This study will address the design and concept of future Cosmic Microwave Background (CMB) experiments and in particular a future CMB satellite to extract cosmological information from the polarized CMB photons. The research will aim at deriving forecasts of the optimal (instrumental and observational) parameters of future CMB experiments, considering technical and hardware aspects along with theoretical modeling, astrophysics and statistics. In addition, the study will address the complementarity of ground based, balloon and space experiments, and investigate how new technologies could impact future measurements from these platforms.

While this work will aim at setting constraints on cosmic inflation, dark matter, light relics and neutrinos as well as cosmological structure formation, it will focus primarily on studying/tackling the challenges posed by foreground emission, CMB lensing, and instrumental systematics, major stumbling blocks for the search of primordial B-modes in CMB data. This focus, and stimulation of demonstrable (and presently mostly nonexistent, given the severity of demands on the requisite measurement fidelity) solutions of the pertinent problems, is necessary for constructive approach to the grand challenge of the CMB cosmology – to obtain credible measurements of the CMB B-mode polarization of primordial origin, and probe firmly the earliest evolutionary epochs of the universe. This work will explore innovative ideas and methodologies aiming at assessing properly the impact of the presence of foreground residuals, lensing-induced B-modes, and instrumental systematics in the CMB maps on the measurements of the tensor–toscalar ratio, r, and the Thomson scattering optical depth, τ.

Our program will help understand what performance can be achieved given novel experimental designs. New concepts for a potential CMB probe and a CMB-S4-class experiment will emerge.

Lodging for out-of-town attendees

There are a number of hotels (5 pages pdf, 181KB) that are close to the Caltech campus where we have a negotiated rate. (Please note that this negotiated rate does not guarantee you the lowest rate as there may be internet specials or AAA rates that may be better.)

Please note that with enough notice, you can reserve rooms for attendees at the Athenaeum, which has been recognized as a Platinum Club of America. Newly refurbished, it is conveniently located on the Caltech Campus. Contact Janet Seid if you would like to check the availability of this option.

Visa Requirements

For Visa requirement information and travel to the United States please visit the website of the U.S. Department of State.

Parking (for Visitors and for JPL Personnel)

For Visitors: From the Arroyo Parkway, turn right (east) on Del Mar Avenue. Proceed approximately one and a quarter miles. The Caltech campus will be on your right. Turn right (south) onto Michigan Avenue. Turn right into the outdoor parking lot and park in an unmarked spot. Buy a parking permit from the kiosks near the middle of the lot or request one ahead of time from KISS.

For JPL Personnel: JPLers may use their JPL hang tag for parking or request a special parking hangtag from the JPL parking office. Employees who do not have on-Lab parking privileges can obtain a hang tag created for this purpose from JPL parking coordinator Robert Kennedy (818-354-4586, Building 310-108B, 9/80 schedule). Please park in the outdoor parking lot located on Michigan Avenue in an unmarked spot.
