Abstract
We study a real tachyon vacuum solution in cubic superstring field theory that avoids square roots and phantom terms. Using this new solution, we evaluate the vacuum energy and obtain a result consistent with Sen's conjecture. Additionally, we demonstrate that the equation of motion, when contracted with the solution itself, is satisfied.
