Exploring the Sun Up Close: The Solar Wind Electron, Alphas, and Protons  (SWEAP) Instrument Suite aboard Solar Probe Plus

The NASA Solar Probe Plus (SPP) mission will be humanity’s first mission to the Sun. The spacecraft will close to within about four million miles of the solar surface in order to observe the acceleration of the solar wind first hand. A key requirement for Solar Probe Plus is the ability to make continuous, accurate, and fast measurements of the electrons and ionized helium (alpha-particles) and hydrogen (protons) that constitute the bulk of the solar wind. The Solar Wind Electrons Alphas and Protons (SWEAP) Investigation is a two-instrument suite that provides these particle observations. SWEAP consists of the Solar Probe Cup (SPC) and the Solar Probe Analyzers (SPAN).  SPC is a Faraday Cup that looks at the Sun and measures ion and electron fluxes and flow angles as a function of energy. SPAN consists of an ion and electron electrostatic analyzer on the ram side of SPP (SPAN-A) and an electron ESA on the anti-ram side (SPAN-B). SPAN-A and -B are rotated 90 degrees relative to one another so their broad FOV combine to view the entire sky.  The talk will describe the science motivation for Solar Probe and specifically SWEAP, the instrument designs, and the expected data.  SWEAP measurements enable discovery and understanding of solar wind acceleration and formation, coronal and solar wind heating, and high-energy particle acceleration.

General Information on NES/OSA Meetings

Cancellations and No-shows:

If the meeting must be canceled for any reason, we will try to call you at the phone number you leave with your reservation. Official notice of cancellation will be on our answering machine.

We have to pay for the dinners reserved as of the Tuesday before the meeting, so no-shows eat into our cash reserve. If you will not be able to attend, please let us know as early as possible. Otherwise, no-shows will be billed.

Membership Rates:

Regular members $15.00
Student members free

 

 

 

NOTE: The extra $5.00 of the non-member dinner fee can be used toward membership dues if the nonmember joins and pays dues for the current year at the meeting.
