Yes.

Yes. Judge Sweeney's 15-year appointment as a CFC Judge occurred when Sweeney was confirmed by the Senate on December 14, 2005 and she entered directly into her duties. President Trump designated her as Chief Judge on July 12, 2018. Chief Judge Sweeney's term expires around December 14, 2020. Chief Judge Sweeney is currently 64-65 years old.

Chief Judge Sweeney replaced Chief Judge Susan G. Braden who was appointed to the U.S. Court of Federal Claims by President George W. Bush on July 14, 2003 and appointed chief judge by President Trump on March 13, 2017. Braden's Term ended on July 12, 2018, 15 years after her 2003 appointment.

Not sure what is meant by a regular judge.
