The US Constitution is not a very long document, so I encourage you to read it if you haven't already.
Article 3 Section 1 states that the Judges on the Supreme Court and the federal courts hold their office during "good behavior." This has never been challenged before, so the definition of "good behavior" hasn't been firmly established.
Any federal judge can be removed through the impeachment & conviction procedure which requires a 2/3 vote in the House and Senate respectively. Interestingly, the Chief Justice is supposed to preside over conviction proceedings in the Senate, but the Constitution doesn't specify who presides if it is the Chief Justice being impeached.
But ultimately to answer your question, the US Constitution does not provide the same special protection from arrest that Congress enjoys. We can speculate why this is the case, and I would argue that this is because the Judiciary was never supposed to be political; it is supposed to be an impartial organization that judges disputes. But Congress is extremely political and as such it'd be more likely to face arbitrary arrests than Judges.
